I agree that it shouldn't, but it is. I need only talk to my mother, she has some very strange ideas of how to raise kids, explaining a lot of my knee-jerk reactions when communicating with my own kids.
My mother told me recently that my six-year-old nephew's personality was already set in stone, and his occasional bursts of energy were proof he needed "tough love" and "a wake-up call," including changing schools. She also seems to have forgotten that my father hit us with his belt. Very strange indeed.
