It has a been a busy weekend. First, I went to an astronomers convention on Saturday. Sunday, I spent grading. Oh, how I hate to grade. It was always one of the drawbacks to being a teacher. With my new teaching gig, they have grading deadlines. Ugh! I’m tired and a bit down today. My parents were supposed to come visit at the end of the month, but for the second year in a row, they have backed out of visiting. This always gets me down. I haven’t seen them since Christmas, and they promised me they would come this year since they didn’t come last year. Anyway, it’s just disappointing.
