Fran, I do see your point. And I see how that might work with a teenage daughter. What I'm talking about happened when I was 10 as I was just starting my journey to womanhood. I know from observing my friend's daughter that there is a HUGE difference in maturity between a 10 year old girl and a teen. There's just no comparison. I don't know that it's possible for the mother to explain away inappropriate fatherly behavior to a 10 year old. The child simply would not have the maturity to understand human behavior enough to be able to view the behavior in this context.
Edited to add: And she shouldn't have to. Why is it the child's responsibility to understand the parent?
