We used to have a seaside holiday in a little bungalow owned by the parents of one of my dad's workmates (so he got mates rates). Low key holidays, just us kids playing on the beach on our own all day and everyday, getting sunburnt, rainsoaked, windswept and everything in between, while our parents relaxed (well, dad did - mum still had to do shopping and cooking and cleaning and washing up, it was the 1960s!).
At home in the summer holidays, I would call at my friend's house down the road and we'd go out for long walks in the countryside together, or sometimes I'd go with my sister and her friend or sometimes all on my own. I used to ride my scooter around the housing estate (on the pavement) on my own. Children generally had a lot of freedom. Often my mum had no idea where I was or when I would be back home! But she trusted me to be "sensible" and not do anything dangerous (and most of the time, I didn't!).
At the time, it all seemed quite ordinary and humdrum. But looking back, it seems wonderful. I feel I was very privileged to have been a child in those times. We had so much freedom and autonomy from such a young age. Most children were out and about, unaccompanied by adults, from the age of 6 or 7.
