They were playing a game online, and in voice chat, the other boy is DS's friend from school, apparently another friend invited this friend and he had go off Minecraft, DS kicked him from the game because he wasn't doing anything. He called DS a bastard and a worthless piece of shit. I think think the first is disproportionate and the second is horrible. Especially as DS has self-esteem issues anyway. DS has asked if I was going to tell the friend's mum. Should I?
