My dad used the belt on me. The Principle in my school used a wooden paddle on us.
I was born in early 70's and was in public school in the 80s, and we still had corporal punishment (in the state I was in).
I haven't heard any physical abuse that would have had CPS involved, for that time period. It all sounds so embellished. If she were really abused, she would have many, many DETAILED stories to reference. These types of things are seared into minds. Details - not like her 'way too general' style of details, but real details - would be used when describing what she went through.
For instance, she said, "my mom began carrying a wooden spoon in her purse"...too general. She would have remembered the EXACT action of that spoon, if she were truly physically abused. Those types of events have a way of slowing down time and are remembered in slow-motion style.
She sounds like someone reading a story, or the explanation of an action, rather than remembering the action. Like, if we were to read something to explain the abuse that someone went through, we may read "she suffered through.....her mother reached for what ever was in reach....she felt alone...".
When someone remembers something that happened to them, they say things like, "I remember her grabbing me by the neck and throwing into the table and I just didn't understand what I did"
