I have no issue helping people when I offer to do it or they are polite in their asking. What I don't do is help people who just invite me with no prior warnings or talk to see if I am available/in the mood (giggity). Catch me when I'm tired of farming Spinmetal or getting fed up with RNJesus in the Crucible, and you might just get lucky and score a level 30 for whatever it is you're trying to get down. Catch me when I'm in a bad mood or spam me with useless invites and you might just get lucky and score a Block Communications.
