I see this was your first post, BluePineapple. Welcome to the boards.
Adam sounds like an extremely insensitive lout, so I'd exercise caution around him if you decide to maintain your friendship. Just a thought, though...if the event involving you happened three years ago, it's kind of sad that it still gets under your skin so much. For me, at least, hanging on to resentments for years can be kind of toxic & counter-productive. It might be different for you, however.
