My keys hang on a hook by the back door, on an inner doorjamb. If you look in the window of the back door, you can't see the keys hanging up there. My purse ends up near the dining table. If company is coming, it eithers goes into a closet, or the sideboard.
Until just very recently, the back door stayed unlocked during the daytime. That changed, when two men raced through my front yard, one of them yelling at the other to stop. I ran outside, and asked them what they were doing in my yard. The one called for me to call 911, as he was chasing a thief. I did so, then followed them in the car. (Yes, I locked up when I left.)
Seems the guy had tried to steal a bike, but was chased off by the owner. Their running through my yard made me realize I have to keep all doors locked!
