I live in a real small town and haven’t seen my house keys for years. The key to my truck is in the ignition where it always is.
I was just telling somebody the other day about the Western PA neighborhood I grew up in...none of the houses had central air and during the summer we’d just leave the windows and doors open with a screen and fans, and they generally stayed that way from late-May through September, only getting locked up when the family went on vacation.
