My mother couldn't have cared less where any of us were, I think her mother was the same with her and my aunt and uncle as long as they turned up for tea. My cousins and I aged between 3 and 11 would all be shoved into two rowing boats for the day on the Thames, near Runnymede, with a picnic to have on the anchorwick. We would catch tiddlers and paddle and swim and almost go down weirs...
My own children now 29 and 19, were not allowed anywhere on their own until they were nine. Even that would be just to go to sweet shops and the library while I was shopping. Or a hundred yards away to a friend's house. Moving back into the countryside, things relaxed hugely. My son aged 12 was travelling along the river in a dinghy to the next town with his friends, just as I used to, and they walked for miles to the nearest swimming lake. Ex was livid was he found out that I was allowing DD to go around the town shopping with her friends, aged 14! Yet only the previous year he had made her walk back to a nightclub in Corfu at 3am all on her own because she had left her purse behind.
