Felt fine, got to work, worked for a bit, then jogged (not ran, thank goodness) to the men's room and threw up (a little, but not in my mouth) and then said "Shite." (No, I did not throw up OH MY GOD DON'T SAY THAT CHRIS.) Wrapped up as hella-quickly as I could and bailed, and now I'm home with enough of a temperature (98.5, which for me actually is higher than normal) that I'm glad I can rest.
I have my work e-mail open for a bit just in case something last-minute comes up; it's a busy day at the office. (I was scheduled to drive my boss to the airport. Me in an enclosed space with my boss for half an hour? BAD IDEA. One we're not doing.)
