Quote from : Indiana Jones and the Last Crusade Movie

Indiana Jones: It was just the two of us, dad. It was a lonely way to grow up. For you, too. If you had been an ordinary, average father like the other guys' dads, you'd have understood that.
Professor Henry Jones: Actually, I was a wonderful father.
Indiana Jones: When?
Professor Henry Jones: Did I ever tell you to eat up? Go to bed? Wash your ears? Do your homework? No. I respected your privacy and I taught you self- reliance.
Indiana Jones: What you taught me was that I was less important to you than people who had been dead for five hundred years in another country. And I learned it so well that we've hardly spoken for twenty years.
Professor Henry Jones: You left just when you were becoming interesting.
