Anyway, there was a bit of a snafu, because the teacher had lost track of the date and didn't know the class was starting today. Oops! So she was 40 minutes late for a 50-minute class, and I didn't get a chance to talk to her. But I will approach her next week and ask if it will be okay.
Also took Cobweb to the vet today, because Shannon and I had become concerned about her weight loss. She has lost more than 3 pounds in the last year and a half, and it's quite noticeable. The vet seemed quite concerned and said we'd done the right thing by bringing her in. Apparently this is really not normal. The vet is going to call us tomorrow with results on some blood and urine tests. I hope it's something not-too-serious and easily treated. I'm trying not to get too worried.
Well, it's off to bed with me.
