What I did was this: I was checking the mail, got my package out of the package box, then went to my car and drove home ~ not realizing I had left my key ring in the key slot of my mailbox.
This means that whoever grabbed my keys can get into my mail (which I promptly put on hold), and worse yet, my house. I suppose if they were so inclined, they could get into my filing cabinet, although there's not much of interest in there.
Luckily, Romeo is home 98% of the time. He just drove to the hardware store for a new door lock assembly. Although ours has a keypad, it can also use a key. And since the person who has my keys can get into my mailbox, they know our address.
Least of all, I have lost my favorite key ring, which I've had for over 25 years. But as I said, that is the least of my worries.
Not my favorite day, and boy am I stupid.
