Not anymore really.
Not trying to sound anti-social or paranoid, just that in my experience 'the drama' (often produced by alcoholics) will eventually find you. That just leads to your life getting more complicated and stressful on a few levels.
The guy you share an office with gets drunk, tells you things about other coworkers and/or himself that makes you wonder if you should tell the police. Your 'office wife' has a bad week and decides to cross that line leaving the Xmas party, lays one on you and goes for your zipper... seconds before your boss smartly swings into the parking space alongside your door. Or you just have a good old fashioned misunderstanding with someone after hours, and their hurt feelings affect any and all collaboration with that person from then on.
I guess what I'm saying is unless it's a strong friendship involving trust, existing before the job maybe, it's easier having acquaintances who can't get you fired.
