Don't smoke before school if you just do it to fuck school off. I did that my freshman year and now my senior year I have a bunch of classes to make up. But yeah, getting high before school is fun for me because it makes it more interesting...and if the teacher's talking, I just listen to them and do what I'm supposed to at school. I'm sure most people know I'm high, but really don't say much considering I don't act like an idiot or show definite signs of intoxication..
