when I was 13 years old, I saw an old book from the 1950s
Youth: From 11 to 16.
I read it cover to cover. I was able to translate “jazz records” to “heavy metal cassettes” etc as behavior is behavior even with a 30+ year difference between the book and me.
And I was shocked how much matched to me at 11, at 12, and then at 13 where I was.
So then I peeked ahead to 14…. to 15…. to 16!
It was like getting a glimpse into T H E F U T U R E.
I had some idea what behaviors I _might_ do before I even did them.
And when time went on and I found myself doing those typical things I remembered the book and laughed to myself:
“You made it!”
and so, when I read other “ages and stages” materials and learned about “nesting behaviors” and such and other categories for 30s, 40s, 50s, etc – – I wasn’t surprised when my time came and I _did_ the things they said I would.
