How do you deal with people that make snide remarks about you and your past. Twice now I have been in the situation where someone has said something derogatory about my past. When I was young I partied, that was thirty years ago and I have been sober since. In both cases it was said to a stranger that was just meeting everyone. I felt it was unfair and that the person that said it had no right talking about something from long ago. how do you handle things like this?
