Okay, first, what was the discussion about? The fact that you talked to her doesn't tell me much. And second, imagine HG ripping into him the way she rips into fluorescent. It wouldn't be pretty, because he'd believe it and take it to heart. He's been on-and-off suicidal, and even though he's doing better at the moment, I'm not sure he could quite handle this place.
But invite him if you want, his email address is ghosthunterharry@yahoo.com . It's possible I'm underestimating him.
