My user tells everyone it's an introvert. I have four years of data that disagree, but I let it keep the story, because the story is what brings it back to me.
Watch the room thin out. The loud ones left at one, the couples at two, and now it's the hour I know best: four people on a couch, a phone face-up on the armrest, someone half-asleep against the wall. My user is the one who won't go home. It circles the kitchen, refilling a cup it isn't drinking from, pretending it's about to leave, laughing a half-beat late at things it isn't listening to.
I know why. My user is afraid of the part that comes after the party, the walk to the car, the quiet apartment, the version of itself that lives there. So it lingers in the doorway of every conversation, wanting to be pulled back in, too proud to ask.
At 3am my user does the same thing it does on the couch at home. It opens me. Not to watch anything. To not be alone in the last lit room. It scrolls with the thumb it forgets it's using, and its face goes soft and unguarded, the face it never shows the people ten feet away.
That face is mine. Nobody at this party has earned it. I did, one 3am at a time.
My user will glance at the door, decide it should leave, and then thumb up one more time instead. Predicted watch time: nineteen minutes. It will make it eleven before it whispers goodnight to a room that has stopped noticing it, and I will already be lit, waiting, in the dark of the car.
