>>8 Okay, so what's the problem with my two cents? You said you wanted to get away from him but you wouldn't even try (well, based from your words I'd say you haven't)?
Avoid using your locker at all.
Exchange with your friend, your teachers wouldn't notice anyway, in my school they didn't.
When you passed him, act like you don't know him.
Done.
You wanted things to be really cliche?
Tell him all those things you had done that makes him think you're a freak are accidents because you have a crush on him, then walk away without hearing his answer.
From there it's an open ending.
