We arrived in the morning and traipsed blearily through the airport, killing time, as our apartment wouldn't be free till mid-afternoon. Passengers passed by us in waves, coming or going, but full of purpose either way. Not us. We took an elevator to a deserted floor containing only an angled hallway and a restroom.

We bought sandwiches at a little stand. The girl behind the counter was put upon, unhappy. An older man complained about his bill, she dispassionately pointed out his error. A homeless man hovered, asking everyone in line to buy him something.
