I would want to know about my dad's childhood, things he liked to do or to play with, and all about growing up. How things have changed now from when he was a kid. Different traditions his family had and ones he carried over into his own family. Things he struggled with and what he did to get through the hard times in life. What makes him happy and can always put a smile on his face. Goals he had or does have, and I would want to know about his dreams. Memories he has with each of his kids and with his wife. Maybe advice he has for the family for the future and lessons he has learned from life. I hope this helps.
