A lot of experiences here similar to mine. Our back garden backed on to a stream which fed into a pond, from a very early age we were under a gap in the fence and playing round the stream and duck pond. Beyond the duck pond was a cricket pitch and beyond that was a common, this was my stamping ground from a very early age.
Often my brother and I would walk, with another girl who lived nearby possibly a mile to and from school, sometimes our mother would be take us and meet us after school but not always. Later on I would walk to and from Brownies held in our church hall, probably half an hour away. School holidays we were out all the time playing in and around the common.
I think most of us suffered from a benign parental neglect which probably developed us as people and helped us stand on our own two feet. I just don't think parents fretted over their children the way that became the norm, certainly when my children were growing up. I can remember on Christmas Eve, having gone to bed earlier, our parents trying to raise us to go to Midnight Mass, if they couldn't do that, they just left us in the house and went off. I'm sure that would be illegal today given our ages.
I think as children we had an innate sense of danger. One school holiday, aged about 10, I and a couple of friends got the train to nearby Box Hill, a few stops away, lying on the grass having a picnic we were approached by a man who got talking to us, firstly about innocuous things like school, he eventually asked us whether we were wearing any underwear, what colour etc., we just scarpered as fast as we could
