They stand talking to each other on the platform. Both: short-cropped, brittle hair, winter coat on over the suit, the jacket, longer, sticks out from under the coat, a large packed backpack on their backs.

I get off the train and walk to the steps. In front of me walks a man with silver-gray hair. He is wearing a black nylon jacket, black pants with a crease, black cotton sports socks, and those solid Ecco shoes.
He confidently holds his thick computer bag in his hand. He must have brought home a lot of papers.
He reminds me of someone. Taut. Inflexible. Straightforward. An architect.

The next day, he walks past me again. Usually, he is all in black, as I just described, but this time, he is wearing a deep, dark brown suit.
