You know, back then, the last thing teachers thought of was abuse. It wasn't known how widespread it was, and they weren't trained to spot it. I went to school with numerous broken bones, black eyes, bruises on my neck...etc. The teachers never noticed anything. They would write that I was lazy, because I would fall asleep during reading in the early grades. Um, maybe because I wasn't allowed to sleep at night? I wrote a letter to my grammar school a few years ago begging them to notice when kids aren't doing well at home.
