As I write, a friend of the family, along for our Chicago adventure, lies doped up on antibiotics in South Suburban Hospital, fending off sepsis. She was peremptorily admitted last night, released, and then admitted again as a precaution, since she's flying home today. A lesson for you, no matter what your age: don't swim in Lake Michigan after popping a blister. And don't ignore your swelling ankles and the nasty red streak on your leg. And don't wait 'til it starts to hurt. And don't say "I'll have it checked tomorrow after we get home."
Meanwhile, just in time for a drive to see friends in Champaign, my head cold is dissipating like a tornado.
