I had only seen a man and woman standing in the driveway once, so I assumed they were just a couple.
The man was tall and broad-shouldered, with a habit of scanning the street as if he expected someone to be watching him.
The woman, who looked a little younger than I was, kept her arms folded tightly across her chest.
Neither of them looked my way.
After that, I mostly noticed signs that someone was living there without actually seeing anyone.
The curtains closed before sunset.
A car left early in the morning and returned after dark.
The back porch light glowed at odd hours.
I had no idea children lived there.
That was why I was so confused the following Tuesday when I went outside to bring my empty trash can back from the curb and realized it felt unusually heavy.
