I guess speedy wit, and sometimes an ability to get an unpleasant point across using humour.
Patience, no real temper or violence in my nature.
Despite my username, (which is more just a warning that I find black comedy funny, I think if you laugh at something, you've just given up your right to be offended by it), I do think I'm fairly positive, and think there's good in nearly everyone, despite being proven wrong regularly, heh.
I run a newbie friendly guild on WOW, and we've been screwed over quite a few times, but the good guys that have come from it, more than make up for losing some items and gold.
Similar to some of the above, a good listener, a caring nature, all the things that immediately dump you in the 'friend zone' while every woman you know goes off with the biggest bastard possible despite your warnings, gets dumped, and comes back to cry on your shoulder, then recovers to go hunting more bastards, safe in the knowledge you're there. *grumble* Come on ladies, there's more to life than pecs.
