It definitely has to be Dobby's death!!! Dobby is such a hero, he literally gave away his life to save the others.

The end. ='(

I was a wreck most of the time, but I literally sobbed like a baby when Hagrid was forced to carry Harry's "corpse" and everyone started screaming when they saw him. Professor McGonagall's reaction really got me, since she has always been the embodiment of strength and methodicalness to me.
Also:
- Dobby's death!
- Fred, Tonks, Lupin, Snape.... sigh.
- Colin Creevey's death! So sad! "He was tiny in death." I feel like crying all over again.
- Dumbledore saying "You wonderful boy. You brave, brave man." got me super emotional.

Aaah, there are so many sad parts. :-(

same with you
- sad when

- Sirius died
-dobby died
-many died in the last war
-Dumbledore groaned in pain when inside the cave and harry persuade him to drink liquids continues

I would say the saddest part of the book was how dumb she made Voldemort look. I mean he could of made anything a horcrux, but he makes obvious things horcruxes making it way too easy for Harry. Another thing off the top of my head, is that he takes Narcissa's word that Harry is dead rather than checking himself. That is just flat out stupid.

Definitely freds death.

Deaths, so many deaths. Sirius and Snape hit me hardest..
Snape's memories..
When Harry saw his parents and godfather before his 'death' ...
