Same. I just want a simple office where I can work for eight hours in relative peace without the assumption the workplace is a bar/club/social gathering. I don't want a place where the assumption is that everyone should be friends and hang out with one another and treat the office like a college dorm.
Unfortunately, it seems the average startup environment (not even just in Silicon Valley) is closer to a college fratenity than a workplace. It's like a lot of these people want to live like college students into their thirties and forties...
