At the end of the Camelot shindig on Saturday, I came down with A Thing. It hasn't gone away, so I just did a quick visit to the doctor -- that told me pretty much what I already expected, but I figured it would be a good idea to get a sanity-check from someone who knows what she's talking about.
Short version: it appears to be a virus, fairly mild but not entirely trivial. Slight fever, sore throat, some coughing, pretty bad fatigue, mild chills. May still be contagious until the fever completely breaks. She expects that to be well before the weekend, which is good, since that is full of things I'd be really annoyed to miss.
In the meantime, I've asked bess to run dance practice this week -- while I might be able to do so, I suspect that I'm too foggy to do a good job, and I don't want to chance passing this on to folks attending practice. (In exchange, she asked me to take a dozen eggs off her hands, a payment I'm happy to provide.)
So that's pretty much the story. Don't know whether I caught this at Camelot, or had it before then and it just didn't manifest until Saturday night. My apologies to everyone if it turns out that I had it then...
