Oh yeah I've had this one big time in the past. It sort of comes and goes, hasn't been bothering me much lately. But a few times at my old job I drove all the way back into work to verify I'd locked the door when leaving for the night even though I was _very_ conscious about locking it - I just wasn't was totally certain as I felt I needed to be.

If this starts bugging me again I'm going to start taking pictures of the locked doors for myself. :)

Have you tried balancing this urge to return, against self-anger and humiliation at all the time and gas you're wasting by driving back to check?

When I get irrational urges, I make the urges battle my insecurities and get out of the way. Insecurities usually win.

I used to do it too. I figured it was a short term memory flaw, then it became a habit, so it just feels "off" to not double check. I'm actually comforted seeing i wasn't the only one.
