I just finished washing my hands. It's not a particularly odd occurrence for most of us (and it isn't for me either). Usually we wash our hands after hitting the restroom, before preparing or eating food, or when you've been touching something like dirt, paint, or grease. I can be a little more obsessive than that: I'll wash my hands after touching a stair bannister, working on a public computer, or after being outside. Not all the time, mind you, it comes in waves. And today was a wave.
I think today's hand washings were related to the weather--it's warm and a little humid and my hands just felt grosser than usual. It doesn't really matter, until, of course, it becomes imperative that I wash my hands.
