I actually wanted to ask this question yesterday but the "What are you afraid of thread' reminded me about it.
Do you lock your doors? What is the extent of locking them? Cars?
When I lived outside DC everything was locked multiple times. Deadbolts, chains, etc. Now that we've moved to a safer area my parents laugh that we put deadbolts on our door, and our neighbors always laugh, in a friendly way, when I lock my car.
My parent's don't even own a key to their house, and haven't locked their door is over 10 years.
