If I may please add to this-- when you have someone in your house, such as a repairman, plumber, carpet cleaner, etc, DO NOT take for granted they are honest. If some one is in your home, regardless of how uncomfortable you may make them feel,, stick close, keep your eyes and ears open.
It only takes an instant for someone to steal something like a gun or jewelry that's easily put into a pocket, tool bag, etc.
Just be aware that it CAN happen to you in your own home!
Hopefully my loss and my posting this will make all ,or at least some,to be more alert when and if you do have someone in your home.
