We arrived in Ann Arbor, checked into the Air B&B and then picked up Jay and Carl at the airport. Late supper at Fraizer’s Pub, followed by another episode of Ken Burns’ American Revolution. Somewhere along the way, it became apparent to me that these people are not well. After spending two weeks with three grandsons, all of preschool age, Jay and Carl have become infected. As Carl said today, “We should have visited Harry first.”
