[Not_here]

I agree with Always here. It is a silly rule and personally I had my fair share of obnoxious uniform rules that I can tell you if you're interested. But then again, if you don't want to get in trouble then following the rules is the answer. When you go into a school, you are signing an invisible contract to give up some of your liberties. If you want to challenge that, more power to you but I wouldn't be surprised if their reaction to your resistance is kicking you out, as sad as that is. Keep the consequences in mind and then you're free to do what you want.
