A woman was caressing her boyfriend’s face and reading Bible verses to him on the train. He stopped her to explain how much she is going to love his church because it has a team that marches to a nearby nursing home and wheels the chair- and bed-bound residents down the street, up escalators, and to the services. I imagined what such a procession must look like — wouldn’t those bed-bound bodies just roll out on the stairs? — and then I realized that perhaps I missed the most important part of their conversation, which I discovered had turned to their mutual love of a Leviticus verse. Yes, I thought, I probably did.
