I met Brian about one year ago on the street. He is homeless and struggles with heroin addiction.  Whenever I see him we stop and talk for a while. I really enjoy our conversations about a wide range of topics as Brian is insightful, intelligent and incredibly frank and self-aware when it comes to discussing his life of addiction. I hadn't seen him in a while because he relapsed and was ordered by the courts to an in-patient drug rehabilitation center where he spent almost 2 months. This was the alternative to a jail sentence for violating his probation by testing positive.
