Seriously, don't set things on fire anymore, especially not at school.

I got suspended for a bin fire which I had to take the blame for...Two years on, and the guy who really did start the fire finally owns up to it...Grrrrr.

Anyway, your friend doesn't sound like the sort of guy you should hang around with, especially not if he's the one who sets stuff on fire a lot. I'm not trying to be your mother, but maybe you should think about trying to make other friends?
