On the way home from Ann Arbor, we realized that Elliot had a fever. His wee head was all warm, and he was hoarse and sad and weepy, and also coughing (hard enough to puke up his lunch at one point). He was in sort of a pitiful state. So we got him home, washed him off, and put him to bed, feeling glum about him and sorry for ourselves a bit, too.
But sleep has fixed all things.
