As a 13 year old, I certainly didn’t have to check in all the time with my parents
Heh. As a 13 year old in the school holidays, way before mobile phones were even on the close horizon, I would be out from 9am till dusk, in town and out and about with my friends. I even had a Saturday job in a café at 13, which was probably illegal, as you had to be 14 in those days, to work in an official capacity. At 14 I worked as a Saturday girl in Woolworth's, and met my friends afterwards to socialise. My brothers had paper rounds at 6am on their bikes, aged 12 onwards.
Nobody had mobiles to let their parents know what they were doing, or for parents to check up on them. At 15 you held down a full time job, and you were considered a very near grown up.
These days though, a 13 year old is socially immature compared to their grandparents, and I think this isn't helped by the fact that technology allows parents to be always 'watching them'. They don't develop, or are not allowed to develop, any autonomy or responsibility for themselves.
The only tabs my parents had on me, was that if I wasn't home by 10pm, then, and only then, should they start to be concerned.
The mindset in those days was so different that it's impossible to explain in this immediate WhatsApp world. Mobile phones simply didn't exist. You just had to trust that your kid was ok. You really did.
Either that, or never let them out at all. And by the same token, kids were more responsible and thoughtful. I knew if I wasn't home by 10pm then my mother would be beside herself. So I always made sure I was home before that. People were in general more mature.
Even 13 year olds.
