Vietnam war vet just left the mental health hospital. He has no place to go, so in a week or two, he is planning to "do something crazy," so they'll send him back, giving him a place to stay and regular meals. Everytime he goes, he is "medicated" for conditions he doesn't actually have. (He spits them out after he leaves the line.)
He saw me while I was waiting for the California bus on my way to work this morning and was very excited to talk to me as he rarely finds people willing to listen to his stories. He asked for no money, just for an ear. He was very nice.
