I don't get it

We went in to work later in the day, which means we had more time to rest a bit. Also, we didn't stay at work as long as usual. We got off around 7 PM. So why am I MORE tired tonight than if I'd worked a full, hard shift?

I am just plain bone-weary right now. Brandon and Kevin both complained how tired they are, too, and also don't understand why. I hope we're not all coming down with some bug!

We don't have to work tomorrow (Wednesday) so maybe we'll all get some good rest and still be able to do some things around here that need doing.
