Sometimes I forget things.
Locking the door when I'm the last one to leave the office is on the list of Things I Forget I've Done or Not.
So after last week's episode of nearly driving the 50-miles one way back to the office to see if I had indeed locked the door, which I swore I did but still doubted and even called the police to have them go check for me (it was locked!), I took my brother's advice and now photograph my locking-in-action.
The proof is in the picture
