We wave with our hands up high, palm extended toward the person to whom we draw near. In the movies, this takes place in a crowded airport or train station, and of course the other person sees you right away, instead of being occupied staring at the candy machine, trying to figure which flavor of LifeSavers to get. No, they see you, give a little wave back, and then, in a trice, the two of you are hugging or exchanging spy information with an undercover agent or shaking hands and heading down to get a cheese sandwich for lunch.
I watch too many old movies on TCM. I mean it.

These ancient customs don't have to be accurate, just ancient.

'Tis said that we shake hands in order to show the other person that our hand has no weapons, but, again, the left hand could be hiding who-knows-what all the while. It's odd. While you're shaking hands to make sure the other person doesn't have an Asian Throwing Star << meant for you in their hand, the hand you're grasping is full of any number of microbial pathogens, and you could wind up with scabies, cooties, or worse.
But at least while you're home getting over the H1N1 virus, at least you know nothing bad was going to happen to you.
This is why I'd rather fist bump!
