why does rules that make no sense and are stupid take so much charge against other people?

The rules that people have to follow in general have some stupid rules. Some of them include what is appropriate to wear to school and other rules. The things that you wear shouldn’t matter. Obviously it just makes the people mad, but they are not wearing it so they shouldn’t worry about it. Another one is why cant you go to lunch somewhere else besides school? That is dumb in my opinion. Yes the school has a good selection but kids should be able to go wherever they want if they pay attention in classes. Finally another reason is why can’t you go through hallways whenever you want? I know you can disturb class but what if you need something for class? that is what i think the school has stupid rules that I don't like.
