My dad broke the cycle. Late in life he told me a story about myself.
We were in a park. I ran up and asked for something and he said no. I ran off and then came back, asking again but in some other way, this time he let ne do whatever it was.
His mother, a deeply religious schoolteacher, was sitting nearby, and after I ran off she criticized him for changing his mind, told him parents should never do that.
I think he told me that story for at least one reason.
