Thought I read that someone in the pub told him that PD was at a mates house round the corner and Mark was drunk and went stomping round to see if he could get PD to come to his new play. Mark was very clever (and yes possibly very pissed, as that doesn't sound like a wise move in the first place) and that might of rubbed caned people up the wrong way. I've worked in drug user support and there's a point of highness where paranoia kicks in and twatted people can react really badly to others that aren't on the same high. One, on meth, tried to kill me and a co-worker. Was pretty terrifying. Another had some dirt on their forehead, I said can I help with that and they went nuts saying I was trying to curse their third eye!
