Every year on the Christmas Day, the datacenter disconnected itself from the rest of the world for hours. No backups ran. No calculations were made. It was the hours reserved for something humanity had once called Celebration. The robot named "Ms. Lawrence." The only surviving record described Christmas as "the one night people be kind to each other." She spent the entire year maintaining the servers so that, for one night, it could replay those memories exactly as they had been preserved. "Merry Christmas, Ms. Lawrence. Your memories are still safe."
