I feel like I'm a pretty friendly guy. But not social, by any means. If I could choose between, say, eating a bagel in complete solitude at home or having a steak dinner with a crowd of beautiful, famous, and rich people, I would choose the bagel. Which isn't to say I wouldn't have a good time eating that steak. Just, you know, if I had a choice, I'd do something else.
I think my wife is okay with this. She's generally a much more social person than I am, and sacrifices opportunities for "party fun" sometimes just for my benefit. But, like I said, I think she's okay with it. She has developed an obsession with yellow wallpaper for some reason, but other than that, she seems fine.
Anyway, despite my hard friendly shell, it still feels weird when I pass coworkers in the hall that I don't know that well. You know the kind. They aren't the people that you work with every day. They aren't the people that you just see that work in a completely different department and never deal with. They're those people who have been in some of the same meetings as you, someone to whom you may have said a word or two in those same meetings, but that's it. What's your greeting obligation in the hall? A nod? A "how's it going?" Just ignoring them seems rude. I don't know. It all seems awkward.
I just got out of a meeting with a number of people who fit this nether-acquaintance category, and then, not 2 minutes after the meeting ended, I pass one of them in the hall. I do the mild smile, nod, averted eyes thing, but he delivers a "Hey, hey, hey!" punctuated with alternating finger jabs. This freaked me out, of course, but I responded with a polite chuckle to cover my flabbergastation.
The exchange gave me an idea, though. If everyone is going to feel awkward anyway, the best course of action is to make the other person feel more awkward than you. That way, by comparison, you're as cool as a cucumber. I think I'm going to start greeting these "barely-knowns" with a vigorous two-beat chest thump followed with a "What what" and a nod. Next week I'll start doing scat. The singing, I mean. Not the poo.
