I'd have so many things to say.

* So WHAT if your science teacher is a jerk, and he's not teaching you anything, and he's destroying your interest. Don't let a-holes dictate your life. Keep at the science. Do well in other areas, then pick it back up in college. Studying music won't get you anywhere.

* Sure, your parents want you to shut up all the time. Practice outside the house. Try talking to other people. And if someone tries to pretend that they're your mother or father, remember that they are not, and tell them what they can do with their attitude.

* Do not think that just because YOU wouldn't hurt a friend or someone you love, that someone who CLAIMS to be your friend or CLAIMS to love you won't hurt you. They'll cause you harm.

* You are a naive kid, and guess what? You'll remain mostly naive until you are almost 50. We need to sit and have a very serious talk.
