When it comes right down to it, which happens fairly often, humans have a very limited library of behaviors to draw from. There's the frustrated, puzzled look humans get when they read a New Yorker cartoon they don't understand. There's the reaching back and pulling their clothing out of their butt cracks. There's the violent jerk of their head when they've just about nodded off at a symphony concert. And that's about it. I suppose there are a few others too gross to mention, so I won't mention them. Like standing up from the toilet and looking down to see what you did. Anyways, waiting at airports is in a category of its own, a category I have named Waiting At Airports. And this is what it looks like.
