I agree with most of the comments.This being on the border line of possibly going negative,I'll keep it positive.I lost my father when I was a toddler.Now I have 2 boys of my own.Although I've never been in you situation,I think I understand his way of thinking, from watching and listening to my boys.Teenage boys want to be physically the same or better than their father and friends.I see and hear my boys saying I hope I'm as tall as Dad or I hope I have a beard like Dads.As I've watched my friends children, go from high school to the adult world,their comparisons change.They go from wanting to be better physically to being better professionally.My son already wants to be a car builder like I was in my early years.I think he'll come around as he grows.He may be looking at you as a role model also.
