Mike discusses how homelessness is dehumanizing. It's emphasized by our unwillingness to interact with the homeless people we encounter. At the end of the book, Mike relates a story about an interaction he had with a homeless person after Mike and Sam came off the streets. Mike gave the man a burrito and visited with him while he ate it. The man said it changed his week.
Simple acts can change all of our lives.
This book would be good reading for anyone, but especially someone seeking to gain a greater understanding and perspective of those who are homeless. It certainly challenged me.
