“Counting on each other became automatic. When I found a sweater in Texas I wanted, I learned to buy two, which was easier than seeing the look of disappointment on Caroline's face when I returned home with only one. When she went out from the boathouse on a windy day, she gave me her schedule in advance, which assuaged her worst-case scenario of flipping the boat, being hit on the head by an oar, and leaving Lucille stranded at home. I still have my set of keys to her house, to locks and doors that no longer exist, and I keep them in my glove compartment, where they have been moved from one car to another in the past couple of years. Someday I will throw them in the Charles, where I lost the seat to her boat and so much else.”
