Glad everything is Ok with your home.

The same thing happened to my mom this summer in Tacoma. A guy rang the doorbell at her house. She looked out the window and didn't recognize the guy so she didn't answer the door. He saw her and asked her through the window if she need any yard work done?
There wasn't any type of yard service vehicle she could see. She said no thanks and he walked off. As he was walking off, she noticed two other guys joining him who had been standing in her side yard out of sight.
She called the police to report it, but never saw any patrol cars drive by. Sure enough, the house two doors down was broken into.
I'm sure glad she didn't open the door.
