I was just walking around in The Castro and ran into an ex-roomate of mine from about 15 years ago. This guy, as I remember him, was a total substance abuser and irresponsible nightmare to live with. He rushed up to me to tell me that he had been in AA for the past year and a half, and that he wanted to make “amends”. He apologized without getting into any of the specifics, we talked for a few minutes, I wished him well in his sobriety, and we said goodbye.
