We don't really want a huge house, but we want the house to be slightly bigger than our neighbors, and a car that is bigger than our neighbor's, and they're going on vacation that's slightly more expensive, and this escalation happens that things got out of hand.

They will only protect you from the mostly honest people who might be tempted to try your door if it had no lock".
