We all say we hate things from time to time. "I hate spinach!" "I hate boys!" "I hate girls!" "I hate you!" How often do we really mean them? I know I've used it casually many a time - "I hate the Eagles" "I hate Pillsbury" "I hate stupid people" and I've rarely meant it as such. It's silly and stupid.
I hate very few things, I think. But I think I hate her. Sigh.
