I guess I kind of understand single people who like being at the office all day but at the same time many of them seem to act like work is most of their social life. That seems bad to me, So your whole social life is at the mercy of your employer? What happens when you get laid off?
In any case just like that guy I have options if I want to be more social. I got a house a short bike ride away from some co working spaces so it's an option.
Totally agree about it being about choice which is a breath of fresh air. Companies in big cities like SF seem like they are run with single college grads in mind.
