Yeah, I just hardly go out on the town anymore, for exactly that reason! There always has to be at least one person who gets drunk enough to be obnoxious. I really don't get it. I mean, where's the fun part?
(The last time I went out with people I work with this one work friend drank too much and started crying and berating her boyfriend for not proposing to her! Awkward! Now I always have 'plans' when staff nights out are planned.)
I'd rather just have a quiet dinner party with people I know well. Or, you know, just chill out at home with my cats! I used to worry that meant I was misanthropic; now I know I'm a misanthrope, but who cares?
