I set the boys bathroom on fire
Why would you set the bathroom on fire?
I tried to piss on burning candles.
That seems dangerous. You should try to be more careful and not damage property that is not yours.
I didn't know it would be this bad, I just pissed on the flame but the whole bathroom is ruined.
Even still, you shouldn't act that irresponsibly. Causing such destruction to someone else's property is terrible and could get you in a lot of trouble.
