Tired

I slept badly last night, since I went to sleep too early, woke at 01:30, and then couldn't get back to sleep for a couple of hours. I couldn't sleep in, since I had an 09:00 class, so I wasn't at my best. Fortunately most of my day was spent advising students on how to make progress with the case study I've set them. Since it's probably the last of the good weather, I took a break in the early afternoon, and walked up Blackford Hill. It's interesting to compare it with the one from Braid Hills Drive, less than 1km further south.
