I'm given to think that life isn't all that complicated after all, in spite of what we hear. Standing in water up to the shoulders or floating with mates is a long established pastime that will satisfy the most active child. 60 years ago I did the same. 60 years before that my father would have found a creek to float in. And before that, his father would have fathomed the shores of Brighton or Blackpool.
How far back do we need to go to find children not playing in the pools of life.
We are not much different to our ancestors. Small gifts bring great pleasure. When it is free it has a sweeter taste.
