I was in class most of Friday, Saturday, and Sunday, and mostly, it was fabulous.

But I overdid it, and I’m getting worried.

On Saturday night, we had a talent/no talent show. I entered, with my friend Dave. Here’s a picture of us singing "The Last Duet" (Barry Manilow/Lily Tomlin).

There’s also a video clip, including the moment when I overdid it. You’ll know.

Immediately after that, Lil Smudge was totally agitated, moving around like he’s never moved before, for about 15 minutes. Then he quieted down. He’s been extra quiet — although still moving some — since then. Also, my lower back hurts.

I’m going to see if I can get in to see the doctor today.
