### Bath Hat

12:05 pm
At the Renaissance Cleveland Hotel this weekend, the toiletries had pretentious names. The "hair wash" was shampoo, the "boot buffer" was the shoe-shine sponge, and the "bath hat" was the shower cap. That made me think of ass-hat, a term for someone with their head up their butt (i.e., wearing their ass as a hat).

For those who are sufficiently circumflexible, "hat" also means symbols with diacritical marks (like "Â"), as used for normalized vectors:

A unit vector is often denoted by a lowercase letter with a superscribed caret or "hat", like this: ${\hat{\imath}}$ (pronounced "i-hat").

I assume a bath hat is what you need if you've got your head up your tub:

As always, I enjoyed seeing everyone. There were only minor weather-related delays for us flying home. Other folks at the airport were delayed even longer, so we got a chance for a bit more chatting.

Oh, and I'm pleased to see a growing assortment of electrical outlets and USB charging stations in the airports.
