My father said, when I was eighteen:

"We think our fathers fools, so wise we grow; our wiser sons, no doubt, will think us so." (He said that when I ridiculed him.)

"I cried because I had no shoes, because I had no feet." (He said that when I felt sorry for myself.)

The next fifty-six years I have tried to live by their admonishments. They have enriched my life.
