As long as the oven is on low and theres little chance of combustion I don’t have a problem leaving the house or taking a nap but I won’t go to sleep with the dryer running..go figger… I seldom lock my doors and usually just drop the car keys on the floorboard, no I don’t live out in the country (jax is a bunch of small towns pulled together under one government) locks only keep honest people out anyway. My youngest daughter recently moved into her own apartment and her roommate is a lock fanatic (a good thing)
