You did not lock the front door of your house? Even at night?!
Wow, we had 8 locks on our apartment door in NYC, and we only locked every other one, so if someone tried to pick the locks, they would lock an unlocked lock, and unlock a lock, lock an unlocked lock, and unlock a lock, lock an unlocked lock, and unlock a lock, lock an unlocked lock, and unlock a lock. And in the end they would still be locked out! Additionally, we had a metal rod that went across the door from the inside, for use when we were home. And we had metal gates on all of the windows.
We could have loaned you a lock if we knew you had needed one! LOL!
But, that was NYC, in the 70's.
