People self harm, yes. I don’t think that gives you any reason to be a douchebag to them about it. Making jokes about self harm is rude as fuck. Saying shit like, “You cut (or whatever else the person does) yourself? That’s stupid.” just makes you an ass. I don’t understand it. Shouldn’t you be NICE to people who feel so low that they turn to self harm? Grow the fuck up and be mature.
