Just as the story reached its climax, a female co-worker walked in and showed her displeasure that we were having such a conversation. I realized that I was with co-workers now, not friends. Okay, so your new company culture sounds more like the one my social worker friend encountered than any sort of young, hip place - you just don't foresee being friends with these people. Simply by virtue of you and your co-workers' decision to enter the same industry, it's probable that you have a mutual interest. Once you get used to the idea of befriending someone outside your traditional peer group, you'll likely find it refreshing.
Boundaries can be a good thing .
While we're not suggesting you fend off traditional friendships in the workplace, it may be easier to have some borders between your work and non-work lives. That way, outside tensions won't creep into your work, and you'll truly be able to leave work behind at the end of each day. 24-7 was just too much. We ended up not being able to stand each other. There are other options.
