I have to admit, I felt like I should be disappointed that I don't have class tonight, but it feels like a relief to be able to stay in my nice warm house instead of teaching all night and then venturing out into a freezing parking lot at 9:30 at night. I'm sure my students didn't mind having the night off, either.
I'm hoping the slightly warmer temps will bring my energy back. I did feel a little better yesterday after a short treadmill run. I will definitely get to the gym tomorrow in case that would help.
