I don’t really remember my maternal grandparents.
My paternal grandmother scolded me one day because I crossed my legs like a girl, and told me not to cross my legs that way. I don’t know if this is the cause, but by now I am not all that flexible and find it difficult to cross my legs one thigh on the other unless I am reclining a bit. Too often I either have to pull the leg into position or my bottom knee presses on the upper leg vein causing my foot to fall asleep.
Besides, I only had short times when I was younger to be able to dress. Sharing a room with 2 brothers and having an older sister and a stay-at-home mom, I didn’t have a lot of alone time.
I never really considered telling my mother, whom I was much closer to. And I certainly felt a lot of shame about it at the time and for many many more years. So no, I don’t think I would have told my grandmother.
