In a few hours he would be flying to France to   36  a different life. It was a transitional（过渡的）time in Daniel's life. I wanted to    37   him some words of significance. But nothing came from my lips, and this was not the    38  time I had let such moments pass. When Daniel was five, I took him to the bus stop on his first day of kindergarten. He asked, “What is it going to be like, Dad? Can I do it?” Then he walked   39   the steps of the bus and disappeared inside. The bus drove away and I said nothing. A decade later, a similar   40 played itself out. I drove him to college. As I started to leave, I tried to think of something to say to give him    41 and confidence as he started this new stage of life. Again, words 42  me. Now, as I stood before him, I thought of those 43   opportunities. How many times have I let such moments   44 ? I don't find a quiet moment to tell him what they have  45  to me.

My mouth turned dry, and I knew I would be able to get out only a few words clearly. “Daniel,” I said, “If I could have picked, I would have picked you.” That's all I could say. He hugged me. For a moment, the world    51 , and there were just Daniel and me. He was saying something, but tears misted my eyes, and I couldn't understand what he was saying. All I was    52  of was the stubble（短须）on his chin as his face pressed   53   mine. What I had said to Daniel was   54 . It was nothing.
