I think this guy needs a warm intervention or something. He basically mopes from board to board, whining about how lonely he is. For some reason I remember him being in better spirits up until very recently. I know he sort of has a reputation for being the sad sack, but it's really gotten pretty bad recently.
I don't know him particularly well, but if any of you guys are close to him, maybe you could ask him what's up. Unless groaning at every given chance about how lonely he is is just his "thing".
