sizemik - We soon broke off the conversation as I realised it was more detrimental for him than for me.
I've experienced the same thing. After one Memorial I attended (some 8 years ago-ish), I recognised someone I knew to be disfellowshipped sitting behind the back row. She was clearly trying to leave quickly after the meeting had finished, but as I sat near the back I approached her just to say 'hello' etc. She looked at floor and said, 'please go away, you'll get me in trouble'. (two elders were watching us)
