As a child I was physically strong. I also did dance, which meant I was much stronger than most of my peers, and a lot of adults.
I was constantly being told not to touch other children during play. That I "didn't know my own strength", and that I might hurt someone. If I tried to say actually, I did know how strong I was, and I knew I hadn't grabbed my brother anywhere near hard enough to result in the dramatic wailing, I was again told I didn't know my own strength, and to be careful when playing with others.
btw yes, while I was strong, in that I could do full chin ups and press ups as an 8 year old, I was definitely not some sort of untrained superhero who hadn't learned to control her powers and went around accidentally breaking chairs and ripping railings from walls.
I always found it interesting that as a girl i was discouraged in this way, while boys were allowed to physically play. I never, ever heard boys being told they were "too strong" to play with others, and if there were injuries it was accidents, and "things getting out of hand", never the fault of one individual.
I was deemed "too strong" for both boys and girls btw. And I never hurt anyone, but I've seen boys break arms and legs playing.
And while I am still reasonably strong, I very much doubt I would fight back if physically attacked. A lifetime of being told I can hurt others easily without meaning to, and learning to hold back and be gentle, I doubt I could overcome that conditioning. I did go to boxercise classes once, and I really can't hit someone with my full force, out of fear I'll hurt them. It's weird, but my brain just can't make my body do it.
