Just read a 1989 Calvin and Hobbes strip about Calvin being deliberately left home alone, unwisely, for a couple of hours. Calvin is 6.

The NSPCC says there is no set legal age and β€œwhile every child is different, we wouldn't recommend leaving a child under 12 years old home alone, particularly for longer periods of time.”

I was babysitting other kids at age 9.
@Pinchy63 You must have been The Responsible One.
@Nickiquote
I sure was. Plus I enjoyed the money.
@Pinchy63 @Nickiquote I gotta know the hourly rate.
@kimlockhartga @Nickiquote
There was no hourly rate. Usually you got 20 bucks for the whole night. Better money if the parents came home drunk which was often.
@Pinchy63 @kimlockhartga @Nickiquote
That's all true except some drunk dads drove you home and wanted to ... give you a tip.... πŸ˜΅β€πŸ’«πŸ€¬πŸ€’
@KarenDorman @kimlockhartga @Nickiquote
OMG yes! I remember walking home many a late night because I didn’t want to get into the car with a drunk dad.
