Was Plato a wizard?...

Nah... Lily didn't think that it really made sense that he would be a wizard, and go out and talk about a hidden wizard city/town. One of the other kids had said it. "I think he was a squib also, only I think that he got mad that he wasn't a wizard so he went out and wrote about Atlantis to get back at his friends who were wizards." That made logical sense. The second year figured that Plato would have been mad to not be a wizard but have lived around them. Who wouldn't if they were constantly surrounded by magical folk but couldn't do magic themselves??
