A couple of man observations

I had a buddy of mine ask if it was okay for a guy to come out of a stall (following a dump) while someone else was in the bathroom. The simple answer is no. Unless you're over 60 you should be staying inside the stall until the coast is clear. And if you do have to leave then you must hang your head in shame, say nothing, and make no eye contact.

Second, two guys should never sit next to each other unless the situation calls for it (like a sold-out sporting event). We go to these lovely town hall meetings and some of the guys in my office see it necessary to cozy up in the seat next to me. That's a no go. There's a one-seat buffer requirement. Like Seinfeld said, if two guys are at a restaurant they don't sit on the same side of the table.
