Oh that's harsh. Well if you parents don't understand you and don't listen maybe you can trick them into sending you to Junior High when you get another teacher or older student to help you with the stuff.
Well I can't help you with the grugs guns knife thingy but no school goes without it. In premary school a boy brought a Ninjy star with him. the teach just stood next to him but I don't remembering him doing anything about it. and the drug thing...well you know this word I think it starts with a N and ends with an O.
Don't be too keen on going to High school or Junior High my first years were hell.
