Lived in the Tenderloin in the mid-70’s, remember it well. Knew more than one guy who had been thrown out by his family, and was making it as best he could. My heart went out to them, and in thanks for my own family, who was always there for me. Later on, left the Tenderloin, went back to school, and my life took many different turns, but some of the guys who were doing whatever they needed to do, to keep a roof over their heads, and food in them, were never disparaged by me. My job is not to judge, but at its best it is to help, to the extent that one can. Don’t beat yourself up for what didn’t happen, you helped for a bit, that is often all that one person can do.
