My 23-year-old son Dan stood in the doorway, ready to say goodbye to his home．In a couple of hours he was going to fly out to France．He was going to be away for at least a year to learn a foreign language and __1__ life in a foreign country．
It was a milestone in Dan’s life, a change from school days to 2 ．When we were to say goodbye, I 3 closely at his face．I would like to provide him with good 4_ that would last longer than here and now．
But not a sound came over my lips．I 5 motionless and silent, looking 6__my son’s green eyes．
I knew that this wasn’t the first time I 7 such an opportunity pass me by．When Daniel was a little boy, I followed him to the bus on his first day in preschool．I 8 the excitement in his hand that held mine when the bus came round the corner．He looked at me —just _ 9 he did now．And then he boarded the bus and 10 ．The bus drove away．And I hadn’t 11 a word．
Some ten years later, a similar experience 12 ．His mother and I drove him to the university where he was going to 13 ．Dan was ill in bed when I wanted to say goodbye． __14 the words let me down．I only murmured something like “I hope you are 15 , Dan．” Then I turned around and left．
Now I stood in front of him and recalled all the 16 when I hadn’t make use of those opportunities．Why does it have to be so 17 to tell your son what you feel? My mouth was 18 , and I knew I would only say a few words．
“Dan,” I 19 stammered out（结结巴巴地说）, “if I had the choice myself, I would have 20 you．” That was all I could say．It was nothing, and yet it was everything．
