Brief conference update:
I've noticed that a lot of my students don't wear watches (they use iPods or cellphones to check the time) and have started paying attention to this when in sessions as well. Some of the people here (mostly men) don't wear watches, either, but I've seen them pull their cellphones out of their pockets and check them quickly, which means, I suppose, that they're checking the time and not their messages.
Yes! We are back to the age of the pocket watch, when men did this all the time, and I think it is charming.
