What did you do with the silence after you left a long career?

I've been retired from the prison for years now, but some mornings I still catch myself listening for the keys. The quiet after a shift was different—it was earned. But this quiet, the retirement kind, it's like a held breath. I'm starting to think it's not peace, it's unfinished business. Did anyone else feel that way when they walked away from something that defined them?
