Around second grade my first full weekend alone was when I was 9. A couple came by to visit and I made them coffee and served them cookies. They later told my parents they wouldn’t dare leave their own older kids alone for the weekend. My parents were so proud of me they saw nothing wrong with it. Of course it was the 60’s and we lived in the countryside. There wasn’t anyplace to get into trouble and someone had to stay home and care for the pets, which were all mine.

Interesting question, same again, how old were you when you were first left alone at home?
