When exactly did you learn that George Washington was the first President of the United States? When did you learn that the Earth revolves around the sun? Who was your teacher when you learned how to spell "cat"?
I sincerely doubt that you remember any of the specifics of these lessons, and yet you've learned them all the same. At some point you didn't know them, and then at another point you did. HOW that happened is immaterial to the fact that it did.
The Life-Lessons we learn in our various experiences are no different. Who we were with, what we were doing, how we were doing it... all take a far back seat to the lesson itself.
The fact that we have learned Love, Trust, Patience, Humility, Honor... These are the things that matter. Not how we come to them.
Some people have learned these lessons already in "previous" experiences. You see them every once in a while: a young child with eerily calm demeanor or empathy beyond what someone that young would "normally" have. You also see the other side of that coin: adults who "just don't get it."
With regards to these lessons, the "who" (Father/Daughter) is far less important than the "what" (unconditional love, loss, acceptance, betrayal, abandonment, grief, joy....)
