I always hear how self-harms are "emo" & "attention seeking". But self harm isn't a joke, it takes a lot to get to the point of turning mental pain to physical pain. When you sit there and make fun of them, you're just making them pull down their sleeves, put on a pair of pants and hide their skin even more. You're pushing them further and further into a hole and if you aren't careful with what you say, the hole will turn into a grave.
