I'll be the only person not drinking and everyone will ask me why I'm not drinking or give me a hard time about it.
You know when I first got sober I thought the same thing, turns out I was very wrong, there were people not hanging around the bar or the keg, they were drinking sodas or tea and having a grand time not drinking. When I was drinking I was with the folks who drank so I thought every one drank, they don't. What I found even more amazing was the people who did drink did not care if I drank or not!!!!
Ask your self these questions "Do I ask people who are not drinking when I am drinking why they are not drinking? Do I care if they are drinking or not?
I was amazed when I went to my first pro foot ball game after I got sober that the line for sodas was longer then the line for beer!!!!
I have found that unless I go to a happy hour (Which I don't) or a keg party (Which I don't) that most people do not drink and those that do drink do not drink like I drank!
