Waving is an odd thing, if you think about it. It’s like, Hello, look, here is my hand. I’m moving it all around because we can see each other! Most people don’t wave that often, but President Obama does it all the time, whether for a crowd or a camera. Not because he necessarily wants to, but because it’s expected of him. The president is supposed to be a friendly and folksy character, and waving as if he gives a shit helps to foster such an image. Usually, Obama pulls it off just fine, with a big happy grin. But sometimes, he just can’t fake it, and the look on his face reveals how grudgingly and unenthusiastically he is performing this charade for us.
