The father cycle, provided you are blessed with a good one:
Tot: My dad's better than your dad.
Teen: You think your old man sucks, sheesh you should getta load of mine.
Twentyish: Maybe I was wrong about Dad, he's not completely useless.
Much Later: I wish I had listened to my father a lot more when I thought I knew everything, and I hope I can live up to his memory.
Condolences, MT. Be greatfull you had such a hero.
