I am in the lock the doors club. My girlfriend is getting better about it lately. When she first moved in she like to leave the door, and a couple of windows open to let in some fresh air. Well a locked screen door would help. Though I can not install one due to the fact that we are in a rental property. a few times I have found the door unlocked. After she saw the reports of a couple of home invasions that happened here in town she is now steadfast on locking the door, and keeping the curtains closed.
I can see how the intruder was in the house for a while without alerting the couple. My hearing is awful (legaly deaf) and I sleep soundly, though my dog tells me when someone is at the door. (You should see how happy he gets when the adorable Girl Scouts come to the door selling cookies.
