Lunch break of awkwardness

So I've already eaten around the outside of my not-cooked-too-well tamale, and decided to brave the outside world to pick up a manual that I should have picked up days ago, and I'm wearing my ill-fitting university t-shirt because it's casual friday, so of course who should I meet but my friend whom I haven't seen in months, who's been out living it up in Sweden and being a fancy PhD student in speech and hearing sciences. So of course he waves me over to say hi and as I'm maneuvering around chairs outside the student union I put my hand down onto the back of a chair, except it wasn't so much putting it down on the back of a chair as it was putting it down into a fresh glob of bird friendliness, and right as it starts to ooze between my fingers he outstreches his arms for a hug. Not to make things more awkward, I pause, wipe my fingers off as best I can onto a different chair, then turn back to him for the hug, being sure I don't actually touch him with that hand. I'm not sure if he realized what was going on, or if he just thought I was insane and maybe a little OCD.

Of course, the awkwardness went both ways, because he had something stuck between his teeth that he was trying to get out throughout the entire conversation that ensued. Aren't we classy.
