My sleepyhead and jet lag

My guy doesn't handle timezones well.

"How are you?" I asked him.
"Sleepy. I sleep all the time. On the weekend, I slept in till 5 pm," he confessed.
"It must be the change in time and maybe weather," I said.
"It could be. I sleep in class, too. I tell my students to do an exercise, and I go to sleep. I wake up, ask if they are done, and go back to sleep," he said.

That's my sweet jet-lagged guy. Luckily, he returns home on Saturday.
