I found out later I should have kept quiet and let the change of my not drinking become obvious sooner or later.
I felt "challenged" and I felt they were putting bets on me that I will drink and make a fool of myself again.
I think they lost if they put on a bet !
When I am asked by those who don't know that I don't drink, I have a few appropriate replies I have picked up along the path of sobriety, one of those,
"no thanks, not drinking today", seems to work.
If I say, "no thanks, I don't drink", or "I don't drink anymore", I have seen the surprise look in their faces or the push for a drink, like, "aw c'mooon, one won't hurt you", type of thing.
I now try to avoid that scenario and if it gets too "hot in the kitchen", I exit the house...no one notices anyway.
