I have always heard of Don Quixote, but I never knew much.  Thank you for the background story.  Why was the story tragic, though?  Is it just because he was crazy?  If he was crazy, but happy - is that still tragic?

I'll show my age here and link to a song from a television show from before most of y'all were born.  This is Scott Bakula singing "Man of La Mancha" in the TV series "Quantum Leap".
