While sitting on the pity pot, the victim bemoans his or her own fate, usually only making comparisons with those more fortunate--those richer, smarter, funnier, sexier, and better looking. And in far less trouble!
"Oh, woe be me!" is a common thought, as is "Oh shit, oh damn!"
Any recovering addict spends a lot of time first sitting on the pity pot and will strongly resemble a baby or toddler at early toilet-training. When addicts finally start to work their twelve step program, they gradually learn how to accept responsibility for their own body functions and actions, do the right thing, and become productive members of society. At this point, the initial work is done, and the addict is able to get off the pot. Who flushes it, is irrelevant. At least the addict has stopped all that whining.
Other: "I love you. I like you."
Pity pottier: "You don't count. You must obviously be a loser too."
Other (groans): "Oh, come on! Will ya get off that pity potty already?"
