I've had a few situations where I've encountered former JW's I used to know, who's
opinions were supposed to matter to me. One time I was dressed nicely for a summer evening out at party at my bosses house. I ducked into a store to pick up some wine ran across a couple that my wife and I used to be close with. For a half second I couldn't place who they were and once I did, I could tell it annoyed them that the person who they were working hard at punishing, didn't even notice all the trouble they had been going through. Once I did recognize them, I went so far as to not use their son and daughters names when I inquired about how they were doing. " How are the Kids doing?" I asked, to which they replied "Ann is married and David is engaged". Then I said in a puzzled forgetful way "That's right...Ann and David...well congratulations....now you guys just had the two kids right??" I could tell it bugged them that I had moved on and wasn't even thinking about their little drama and that my life obviously wasn't the train wreck they'd hoped for.
If I were you Tameria 2001 I'd go looking my best and I'd have a calm contented expression with a gentle smile on my face that conveyed that I was at peace with my life and it mattered not, what happened in the past nor what anyone there thinks of me and in fact I barely even remember anything about them.
If something controversial comes up, just be very vague, have a subtle knowing smile on your face and convey through your body language and demeanor that you haven't the foggiest notion of what they're talking about.
