Most every employee in my office is currently drinking. Not just having some drinks, but full-on partying. I'm not participating because I have to work later than the rest of them but mainly because I'm trying to avoid alcohol in general. Am I going to be seen as a poor sport because I'm not at least hanging out? How do you non-drinker/sober people deal with situations like this? I don't necessarily want to advertise that I'm going "sober" because I don't want there to be any ideas that there could be a problem there. This is something that they don't need to know.
