Growing up, we had a front door that we never used, so we left it locked, and the side door was always unlocked unless we were going on vacation or something.
My friends parents locked their door when they werent home, but they always left the windows next to the door unlocked, so they or I or anyone could just climb in if we needed to.
I dont know if people locked doors at night, but we didn’t. Definitely no one ever locked the door during the day when they were home. The first time I experienced someone doing that, I was so confused. If a thief is willing to go into an occupied house, they’ll be willing to break a window.
I would never leave keys in a car, partly because of where I live now, but also because cars are deadly weapons, and you shouldn’t leave those around where kids could get hurt.

This is “cant” as in “they dont have standing to”, not “cant” as in “they are legally prohibited from”.
Debt collectors can, and often do try to collect from heirs. The heirs dont have to pay, but they often dont know that, and the debt collectors obviously wouldn’t tell them.
