The fact that the guy you are talking about is a very pushy nor'eastern jackass is a glaring omission in your analysis. Unless you are kissing this guys ass you would be seen as stand-offish. This hasn't been a long-term job challenge for you. I don't think it wil be, espescially when you aren't marooned by your boss, working alone, and institutionally forced not to communicate with your co-workers.

of course I am biased.
