Supporting my sobriety is not a requirement for me to have a friend, they can be neutral or still drink and that is fine with me. It honestly doesn't come up at all now unless I bring it up for a reason, like helping some who wants to quit.
Having an acquaintance start to harrass or try to tempt me will bring my silent hairy eyeball, and a walk away never to speak again. Seriously. If they try to use HS peer pressure They get a laugh and the same thing. I can't engage in a battle of wits with an unarmed man or woman.
But I don't think about it one way or the other. Why should they? I remember how I used to hate going to a "family" restaurant that did not serve alcohol. Now I prefer them, and find they have pretty good food too.
In early sobriety there are some social lessons that are tough for all of us. Especially if our relationships were alcohol based. Those can't survive our sobriety for many of the reasons already stated.
