It's hard to tell if odd is odd, or odd is the tip of a very large and shitty iceberg!
People seem to believe that if you had abusive parents, that it's a very big and significant thing to happen, as abuse is such a dreadful thing. But, it's not that simple when you're looking from the inside -out.
I hope my son never feels like I do about my parents, especially my mum. But I console myself with knowing that I would never behave like she did to me.
I spent my pregnancy terrified that I would be the same parent as her, especially as she always said 'wait until you have children, then you'll understand', and also that I was just the same as her. So I was very very scared that I WAS like her and her behavior WOULD make sense.
It was rather amazing in the end. As soon as I held DS in my arms and fell in love with him, I saw my mother for what she was. Never have I felt that much conviction. I don't have it in me to be what she was. And I know I will make mistakes they'll be my own mistakes and not hers.
It was a liberating moment
.
I was so worried I'd turn out like her I was determined to fake love if I was incapable of being a good mummy naturally...
Turned out I hadn't needed to swat up on attachment and how to create unconditional love between you and your child, or read with horror attachment disorders and how they can break a child before they're even a year old.
I was SO happy to find out by having DS that you don't behave like her as some kind of debatable, middle ground, borderline ok sort of thing.
What she did was so extreme, it turns out, and it made me see that no one would accidentally fall into behaving in the same way, unless they were already an extremely warped and unpleasant person.
I still find it incredible that she could ever have normalized her disgusting behavior. Especially now DS is getting to the age where I have 'and then she did this' type stories. Looking at him, seeing what a beautiful, innocent vulnerable child he is, makes her abuse fall into focus. I believed I was to blame, and somehow always felt much older and much more responsible, accountable than I now know could ever have been the reality.
And no, it was never 6 of one and half a dozen of the other. 
Sorry, a long way of saying... Start with 'odd' and as you start questioning, you may come to forgiveness, or clarity, about your childhood and your parents.
You don't have to love them by default. Not if they don't deserve it.
