Team dinner

There's a team dinner tonight which I am planning to miss. I'll go, have a drink at 5.30 and then leave. Since I don't drink alcohol, I find people getting mellow as they are in their 3rd or 4th pint, while I just get to observe them. It's kind of fun! If I could, I'd get out of going at all, but people will wonder what's wrong with me just for missing dinner, I don't want to make it worse by not going at all.
