Do you think it's wrong for me to serve wine at Thanksgiving dinner, although there will be a recovering alcoholic there?
Why do you think you should still serve the wine.
I feel like they will be fine.
Thinking that they have the self control not to want to drink is fine but you should try to be considerate of the fact that they are still recovering. The temptation may make them feel uncomfortable even if they don't decide to drink and ruin the evening for them.
I guess I should still serve it.
I understand that you arre considering your other guests, and that is fine. Maybe you can keep the wine out of view and provide it if another guest asks if you have some wine.
