Did Snape really hate Gryffindor House?
Now, this is one thing that I was a little confused about for a while. I mean, he loved Lily, and Lily was a Gryffindor, so perhaps he only pretends to hate Gryffindor. Because he's definitely not thick enough to still think all Gryffindors are bad when the only thing he ever loved was in that House.
But then again, all of his childhood tormentors were in Gryffindor... So it balances out. Well, it does more than balance it. And plus, he probably hates all Gryffindors because they remind him too much of Lily. Think about it- the Trio especially. I bet he hates them because together, they make Lily. Harry is her son and has her eyes, Ron has her hair, and Hermione is a smart Muggleborn. And they're all Gryffindors. So if Hermione had Harry's eyes and Ron's hair color... She'd almost be Lily. Sort of.
Another thing, do you suppose Snape noticed that Ginny is a lot like Lily? Not just her hair, but her attitude too... If he even knew, then he definitely hated that Ginny was with Harry. That would have been exactly like seeing Lily and James together.
I'm sorry this is so short, but there isn't much reasoning that could be said for this. I suppose it's my fault for using it in the first place. Yeah, I was a bit lazy tonight.
