"You see them, the shadows, everywhere. They look like the person you knew, maybe someone you were related to, maybe someone you loved. Always someone you lost. But they aren’t that someone. That’s the infuriating and the comforting part. They can’t be that someone. They’re the right age, even though years have passed."
