Hmm...
Well I guess from a legal standpoint, it'd be either breaking the windows out of a church and a food pantry (that was back when I had bad friends - one particularly), or me skipping so much school that I got expelled and nearly got taken to court over it.
From a moral standpoint, um...not sure I usually try to be a good person? Although I used to have an odd amount of people come to me saying they were suicidal and wanting advice, but I was like 16 at the time what the **** would I know? I would just say generic things like "Don't, I'm sure there are people that would miss you" and etc., then I'd find a way to bail on the conversation. I wouldn't feel guilty if they did kill themselves though, because it wasn't my fault!
(EDIT: I just noticed how wrong that last sentence looks - nobody ended up killing themselves after coming to me as far as I know!)
