I remember how much my son loved trains when he was young and airplanes flying over.
It’s normal. Not imposed.
When my daughter was little she wanted a fire engine for Christmas. That was fine with us. She is now a highly paid engineer.
Her femininity is clearly indicated by the fact that she still has that fire engine in her forties and it is in practically new condition. Every toy I ever had succumbed quickly to some form of childish physics experiment.
