Now, as I stood before him, I thought of those lost opportunities. How many times have we all let such moments pass? A boy graduates from school, a daughter gets married. We go through the motions of the ceremony, but we don't seek out our children and find a quiet moment to tell them what they have meant to us. Or what they might expect to face in the years ahead.

How fast the years had passed. Daniel was born in New Orleans, LA., in 1962, slow to walk and talk, and small of stature. He was the tiniest in his class, but he developed a warm, outgoing nature and was popular with his peers. He was coordinated and agile, and he became adept in sports.

Baseball gave him his earliest challenge. He was an outstanding pitcher in Little League, and eventually, as a senior in high school, made the varsity, winning half the team's games with a record of five wins and two losses. At graduation, the coach named Daniel the team's most valuable player.

His finest hour, though, came at a school science fair. He entered an exhibit showing how the circulatory system works. It was primitive and crude, especially compared to the fancy, computerized, blinking-light models entered by other students. My wife, Sara, felt embarrassed for him.

It turned out that the other kids had not done their own work-their parents had made their exhibits. As the judges went on their rounds, they found that these other kids couldn't answer their questions. Daniel answered every one. When the judges awarded the Albert Einstein Plaque for the best exhibit, they gave it to him.

By the time Daniel left for college he stood six feet tall and weighed 170 pounds. He was muscular and in superb condition, but he never pitched another inning, having given up baseball for English literature. I was sorry that he would not develop his athletic talent, but proud that he had made such a mature decision.

One day I told Daniel that the great failing in my life had been that I didn't take a year or two off to travel when I finished college. This is the best way, to my way of thinking, to broaden oneself and develop a larger perspective on life. Once I had married and begun working, I found that the dream of living in another culture had vanished.

Daniel thought about this. His friends said that he would be insane to put his career on hold. But he decided it wasn't so crazy. After graduation, he worked as a waiter at college, a bike messenger and a house painter. With the money he earned, he had enough to go to Paris.

The night before he was to leave, I tossed in bed. I was trying to figure out something to say. Nothing came to mind. Maybe, I thought, it wasn't necessary to say anything.
