My wife told me over a half-eaten sandwich, the way you'd mention rain on the way. Then she explained what the dinner parties had really been for.

I drove across town to surprise my husband with the lunch he forgot. His office was empty. His watch was still warm on the desk, pretending he'd never left.

Marcus was forty minutes across the city at his desk. So why did my phone say our oven was warming up at two in the afternoon?

I ordered a car to work like I do every weekday. The app opened, the profile picture loaded, and my whole marriage rearranged itself in three seconds.

He logged a long, lonely trail run on the app I bought him. I tapped one feature I had never used before, and the map answered a question I had not dared to ask.

He swore he never left the house that night. The little app on my phone remembered a different story, down to the minute.
