Hi Ho, Trigger
In the understatement of the year, the environment called 'A Bar' has very differents meanings to you - a non-Drinker - and her [in Recovery]. You can't be triggered there. She could be. So, ask.
Folks here post Triggers that are non-issues for me. However, there's no 'one size fits all' answer possible. Some Folks won't go down the Booze Aisle in a Drug or Grocery Store where Booze is also sold. I have no issues with it. I go to a local Sports Bar, but only for their Chicken Wings. All this moderate immunity to Triggers doesn't mean squat to the next Person because their Movie is different than my Movie.
Four months on, when I get 'stuck' somewhere with Drinkers I don't want to be around, it is not a fun evening. It's work, and I get P.O.ed at myself that I let that happen.
She'll appreciate your consideration in asking, and the evening will go much better.
