If nothing else, you can take solace from the knowledge that you went out, did the washing, and watched tv, while he.....camped you.The odd time i get camped that I don't wanna go to the spirit healer, I'll wait at my corpse as a ghost for hours if need be, reading a book or something, jumping occasionally to prevent afk.

Or I ask for 70's to help me, wait until the camper is distracted fighting them, and join in. That works fairly well too.
