Your phone screams at 9:14 PM. It says: stay inside. Don't answer the door. Even to a voice you recognize.
So you lock the door. You put the chain on. Twice, just to hear it click.
You count your food. 39 cans. 3 gallons of water. You live alone. That's enough for a while.
At 11:52, someone knocks.
Then a voice. Your mom's voice. Honey, it's Mom. Let me in. It's so cold out here.
But your mom lives four hundred miles away. And right then, your phone buzzes. A text. From Mom.
The knocking stops. And the voice says, very calmly: open the door.
