I have worked with the homeless for 25 years. The system has no real place for kids his age. There may be a youth shelter in your community that's where I would start. People have lots of different ideas about homelessness..most kids his age don't do well in any kind of shelter environment. The ones for youth have extreme rules and the ones for adults are no place for 20 year old. They typically become targets for predators or instigate issues. This is based on managing a shelter that held hundreds every night.

Your kindness means something. The posts here about being careful or not extending that kindness are very accurate ...unless the young man is exceptional. If you have the patience you could sit down with him and have him call community resources. If he's not capable of doing it himself and it's overwhelming for you then pm me and I can try to help you.

Book was hot garbage. The pov was written by somebody who did very little research about musicians. The characters were lifeless, the dialog was flat. In my case, it was reading somebody's very poor draft of a book.
