Balconies feel “inside” the house, so people sometimes get casual about their doors. A latch that doesn’t fully catch, a lock that needs a special jiggle – sab chalta hai mode. But at night, or when you’re away, that weak point is easier to exploit than the main door.

You sleep better knowing all potential entries are properly shut, not just “almost closed.”
