lol Francis took the words right out of my mouth. Thank you, Professor.

i would have to agree with that for sure.

But i have to wonder sometimes if there was another sibling before Lilly that went to Hogwarts becauase in the book she says "my parents were so proud when she got accepted to hogwarts" or something along those lines, im sure we all know the quote by now.

So if that is true in any way i wonder why it was never addressed

Petunia reminds of my aunties too. jealous freeks

Does it ever Actually say 'Lilly Was muggle born'? Because I didnt catch it. I think that well... Ill show you my clues and yeah:

The expressions 'pure-blood', 'half-blood' and 'Muggle-born' have been coined by people to whom these distinctions matter, and express their originators' prejudices. As far as somebody like Lucius Malfoy is concerned, for instance, a Muggle-born is as 'bad' as a Muggle. Therefore Harry would be considered only 'half' wizard, because of his mother's grandparents.

This was from JKrowling.com

ok any way why if Lilly's parents were muggles would they skip them in mentioning the muggle and go to the grandparents? So everybody between there must me magical. it might be helpful to make a tree. Is my thinking all messed up? well I think that Petunia is a squib becaause she obviously isnt magical and She was the oldest and a disappointment so when they had Lilly (a witch) they were proud. That is what I think. And that is why she hates magic so much.

Snape called Lilly a mudblood when he was 15. Also her parents were thrilled when she got her letter. If they had been magic then why would that come as a suprise? I don't think that Petuia is a squib because her parents wern't magic, but I think she's jealous and bitter.

Its impossible for petunia to be a squib because your parents have to be a witch and wizard. She probably found out about dementos through her sister as she said because her parents wouldn't know much about magic and its not as if she could go to hogwarts and find out about things there either. but I do agree on her knowing more than she should. She's definately keeping a secret.

well...no, she can't be. a squib has magical parents...lily and petunia don't...therefore she isn't a squib...she just happened to live with a witch thats how she knows all that stuff

yes like everyoen said a squib is someone who is muggle with magical parents, we have been told plenty of times that Lily is a muggleborn therefore her parents must be muggle and Lily and Petunia are sisters and so far as we can tell Petunia is a muggle as well. So no she isn't

I find it very strange that Lily's parents were so pleased and proud to find out that she was a witch. That indicates to me that they knew about the wizarding world, because otherwize they'd be surprised or even shocked wouldn't they? I think there were witches/wizards further back in the family. A couple of things JKR has said bothers me:
(From JKR's interview at Edinburgh Castle

Audience Member: Is Aunt Petunia a Squib?

JKR: Good question. No she is not, but—[Laughter]. No, she is not a Squib. She is a Muggle, but—[Laughter]. You will have to read the other books. You might have got the impression that there is a little bit more to Aunt Petunia than meets the eye, and you will find out what it is.

This "No she is not, BUT - and then laughter" -bit has me thinking that she has some magic in her afterall. And then I read that JKR had said that ".. there is a character who does manage in desperate circumstances to do magic quite late in life" I'm betting this is Petunia. Maybe she's always had some magic in her (and known it) but not enough to get accepted at Hogwarts? This would definately explain her jealousy towards Lily and why she hates everything magic. From a psychological point of view it sounds very logical.
Edit:
Also, just think about it; Petunia has said so many times that their parents were on about how "perfect" Lily was. What a strange choice of words as if being a non-magic person makes you less perfect? That also hints at Petunia having magical abilities and that they are weak, hence she is less "perfect" than Lily.
Does it make sense?

i think Petunia is a squib because it is possible for the parents of the girls to be the squibs. Remember Petunia said in SS that the parents was so proud of Lily for being the witch of the family. Why would they be sooooo proud of her if she is a witch? The parents probably was so proud of her because they thought their children would be squibs like them??? Everything is possble. UMMMM oh man my head hurt to think this hard!

Well, petunia did know about dementors, and she does seem to hate the magical world but also is jealous of her sister because of all the attention shegot from their parents. I love lists so lets list what we know

FACTS:

JKR said Petunia IS a muggle
JKR said that Petunia IS NOT a squib
JKR has mentioned that some people MAY perform magic late in life in desperate situations
Petunia has knowledge about obscure details about the wizarding world ie. dementors.
JKR practically shouted that their is something more to petunia than we think.
JKR LOOOVES her little jokes and keeping us in the dark (lol j/k)

So it logically follows that either Petunia, jealous of her sister, read Lily's text books, developed magic later in life, Lily WAS not the only muggle born with/wizard in the family, or that their family knew someone who was a witch/wizard and learned about the magical world from them.

I think its not impossible but Petunia's parents were muggles. Lily being a wizard and having magic was pretty cool just like Hermione. I think if u were a squib u would have to have come from a wizard family not muggles.

Petunia can't possibly be a squib because her parents were muggles. But I do think that she has to have some kind of contact to the wizarding world. JKR always seems to hint about big things with little comments like the fact that petunia knew about dementors. I know this was mentioned before but i also agree with the theory that she has just a tinsy bit of magic, but at the time when she was eleven and they were accepting students, she didn't have enough to be accepted into Hogwarts.
Just a thought, though i might be wrong.
We'll find out soon though! *((July 16th is drawing nearer!!))*

Edit:
Okay now I know that you can't have a tinsy bit of magic and not get into Hogwarts. I read it at jkrowling.com. She said if you had any amount of magic you would most likely be accepted into the school.

on JKRowling.com it said petunia wasn't a squib, but she is hiding something.

well she very well be... maybe thats why she hates talking about the wizarding world and why she hates her sister and all other wizards and witches.
so yeah i think she is.
or she could just be a muggle who is jelous of her sister because she got to be a witch.

and i have another theory: maybe one of her parents where a squib themselves and kept it a secret you never know.

but i do believe that she is definatly hiding something the question is what is it. *ponders for a long long long long long time*

well i guess we'll find out sooner or later now won't we.
maybe the answer will be in HBP!

well Ozz out.

I'm really sorry but i would have to dissagree with you there for one reason.

#1 if that was the case Dudley would be ether a squib or a wizard.
and since he could not see the dementer that would rule out the squib part. and since he was not accepted to Hogwarts that rules out the wizard part.

and i find it highly impossible that he could just be a regular common muggle
because if patunia was in fact a squib or a witch she would have passed that jean on to Dudley.

and maybe he is the one who will come into his powers but i find that unlikely as well but you never know so that concludes my theory

Thanks for hearing me out.

She can't be coz as far as we know, Lily was Muggleborn, which means that neither her nor Petunia had magical parents.

This is possibly the best theory I've heard yet. Her parents were really excited, or so Petunia said, to have Lily as a witch. Except... if both their parents were squibs, that would make them non-magical, and then Petunia wouldn't be a squib, because a squib is a non-magical person born to magical parents. Being squibs wouldn't make them magical. Did that make sense? But still, I think its a fantastic and likely idea.

I'm not sure if you're right, but I really think its a great idea.

i agree, it's in the back of my mind, but I try not to think about it until it happens.

Lily is muggle born..So her parents aren't wizards..So, Petunia can't be a squib..I think is is jealousy of her sister only..

Wow! I never thought about that before! I think she could be though! maybe.. probably!

i have a quote from jk that someone asks her about petunia bieng a squib

start quote

Is Aunt Petunia a Squib?

Good question. No, she is not, but—[Laughter]. No, she is not a Squib. She is a Muggle, but—[Laughter]. You will have to read the other books. You might have got the impression that there is a little bit more to Aunt Petunia than meets the eye, and you will find out what it is. She is not a squib, although that is a very good guess. Oh, I am giving a lot away here. I am being shockingly indiscreet.

end quote

so no i dont think that petunia is a squib

I agree with what you're saying.... oOohh... this is gonna get interesting..... hopefully....

Petunia would know all the wizard stuff because Lily was invited to the school and she wasn't. She was jealous and turned it into hate!!
