He also talks directly about the misconceptions people have about homelessness and how we need to face those ideas if we are going to help those that we aught to be helping.
It's a good read. Seriously. You will read touching, personal stories about the people that he met, most of them men. You will read how he wasn't truly homeless because he could just leave when he wanted to. You will see and smell and understand more about the grab the street has on some people. How homelessness affects a body, and just how helpful people can be...just because they can be.
Recommend you read it.
