I was nearly done when the knock came at almost midnight. A soft uncertain knock, nothing like the arrival I had imagined all evening. Through the peephole I saw Amber, Kevin’s girlfriend, in sweatpants, holding a square cardboard box from a grocery store bakery. I opened the door.

She gave me a weak smile that barely rose high enough to count and pushed the box into my hands before I had invited her in. Through the plastic window in the lid I could see a sheet cake with bright blue frosting and little white sugar stars. The price tag was still attached to the side. Nineteen ninety-nine, curling at one corner.

“I know it’s late,” she said. “I just thought… I don’t know. Somebody should bring something.”

I looked at the cake. Then at her. Then stepped aside and let her in because whatever else was happening, it was cold outside and midnight is a poor hour to perform total theatrical rigidity.

She walked into the entryway and looked around the way I had seen people look at things when what they were actually doing was calculating. Her eyes moved over the living room and settled into an expression I recognized from long familiarity as envy dressed in neutral clothing.

“It’s big,” she said.
