re: Friends you work with who care about the company

"Agreed, but this guy isn't "working" after hours. He's gabbing and reviewing his day with his partners. It honestly sounds like this is a new venture and he's super excited about it and can't talk about anything but work."

Depending on the work one does and the level one occupies, it can sometimes be difficult to draw the line between what is work and what is just BS'ing with work friends/partners on matters related to work. But the OP should at least ask himself which one is really doing.
