Ok, Mom is getting a call today - we were on the way to school and he made a rude comment, so I asked him not to say that - and he said he wished he'd get struck by lightning, so that at least he'd be dead!
ETA: Just a few days ago I went on and on here about how great my group was - and I included him in that. However, if this keeps up, I'm going to have to ask them to leave, no matter how much I REALLY need that money. Too stressful!
