I'm with everyone else - don't think I could do it either. I'm a couple of months in, and I am still very choosy about my invites to bars. I seriously look at what the occasion is, which bar it is, and who I am going out with. Needless to say, I have only been out twice - once for a friend's birthday with people who I really trust, and once with a close friend who I really trust.
Would your husband be really offended if you left early and suddenly?
