It was just one of those days. I was walking home and it seemed that the person in front of me was doing the same. They were one of the few not looking down at their phones as they meandered up to our front door. But oh. I was too far away. I felt my heart rate speed up. I needed to be faster. My right knee twinged. They had reached the door. They looked back. I looked into their eyes. I saw the key go in. I sped up again. The door fell shut behind them with a heavy click.
