Why do you hate the teacher? Most of the time, you dislike the teacher because you're the dick, and the teacher is treating you like you treat them. It's a general rule of thumb that if you act like an asshole in class, the teacher won't be out to be your BFF. Granted there are a few exceptions, and some teachers really are out there just to be dicks. However, regardless of what the case is, you should probably just grow up.
