That’s exactly what I meant.
When I was little I was a tomboy for a while and refused to wear dresses or skirts (in the olden days when girls almost always wore them). I was not a transgendered anything. The reason? I watched Davy Crocket and Hopalong Cassidy on TV and wanted to be a cowboy or a frontiersman. I don’t think it crossed my mind yet (age 4 maybe or 5?) that I would grow up into a woman; the idea of growing up was unreal (note my comment above about wanting to be an elephant when I grew up at one point.)
It was all play to me, as it is to most children that age. Like when they put dolls to sleep, or feed, them (which I also did) they are sure the dolls really sleep and eat (I thought that).
