Locking your doors is really not that important...well not in the country during the day anyway.
When you live in the city you don't go from here to across the street without locking your door.
Warming your car up with the key in the ignition is a no no...you might go out and find it missing.
Well in the country people don't worry about that. People leave their front door unlocked all day..even if they're not there. That took some time to get use to but now...I can't remember the last time I locked the car door.
its nice to live where people are so trusting.
