One of my former classmates came out of nowhere one day and proclaimed to her friends that she doesn't lock her door. Ever. She said if anyone ever broke into her house, it would be easier to escape. Do you agree with her intentions?
Wouldn't they just walk through the door first? I'd imagine a criminal would watch his prey before attacking it/them. That's why I always have the door lock unless one of my family members are outside. When I go biking or hiking, I have it unlocked, but it'd only for a few minutes.
