It's gotta be science for me, not because of the lessons (I'm always paying attention), but because of the kids in my class. A lot of them are just plain *******s. This group of three kids were known as the "cool guys" of the classroom, and whenever the teacher is gone, they would cause trouble for the others (they even through a tiny cow figurine at one of my friends in the room). They would usually pick on me and my friend because of how we're not the same as the others, like my taste in films.
For example, I hate those silly Fast and the Furious films, they act like it's the best movie they've seen. Best movie ever? When did Fast and the Furious ever rank up with The Godfather, Schindler's List, Seven Samurai, or Lawrence of Arabia? They even beat up this kid I knew because he said he didn't even like those movies.
Also, they never even shut up once when the teacher is gone. They always act like they've just started kindergarten when the teacher is gone, throwing stuff around, etc.
It's basically why I am so annoyed with my science class.
