I know a couple homeless guys that live under a bridge near a bar I frequent. One is kind of 'twitchy' and potentially violent, but I don't see him too much. The other one is named Monk, and is just a burnout in his late 50's (if you ever see the TV show called 'Jail', they have an episode filmed here in Austin where Monk gets taken into custody by the Travis County Sheriffs - long messy dark hair, beard, and incoherent, drunken, Texas drawl - and gets attacked by another inmate). Whenever Monk sees me outside, he comes up and shoots the breeze and never asks me for money. One time when I had a flat tire late at night in the rain, he rode up on his bicycle and changed my tire for me. I gave hime the last 20 I had on me at the time, and then gave him another 20 the next time I saw him. I haven't seen old Monk in a while, but when I do, I'll usually offer him at least enough for a 40 without his asking. His problems are 100% self-induced and he admits it, but he's actually a pretty decent chap in his own way.
