I don’t know why that guy is in AA. He may be court ordered, he may honestly be trying to quit smoking crack or drinking or whatever his problem is. He just doesn’t seem like the kind of guy who would show up voluntarily. Maybe he’s lonely.
Recovery is a great place to meet people and socialize. It's high school with ashtrays and the prom queen is a crack whore. Well... maybe its not like high school at all, but it is a good place to meet people.
