Futzing with things.
Poking at things.
At least I'm wearing my towel. I'm thinking I should start carrying one around with me everywhere, all the time. They really are useful, and my backpack has the room most of the time*. Plus it would act as extra padding for my laptop.
* - Today I really am wearing it, much like a scarf, but I think it'd just be too inconvenient most days. It's a bit clunky, and almost blew away a few times while I was walking to work. So, the backpack.
