I recently noticed that my engagement ring was not in my jewelry box. I don't wear it daily as I often have swollen joints. I can't pinpoint the last time I saw it. It may have fallen off, or dropped somewhere, or it was taken. It may have gone missing over a month ago - not sure. At this point I've given up on finding it. I asked my cleaners and sitters if they've seen it. No one has. Now the nagging question is should I replace all employees who have access to my house just in case it was taken? Seems extreme, but what if I'm still employing someone who took it?
