It’s not easy to be an astronaut’s son.Everybody expects you to be special or perfect. I often wonder how my father ever had a son like me. I mean he’s so special and so good at everything he does. Even in middle school he was class president and captain of the football team.

Well,to be honest,I often dream about being some kind of hero or doing something special—like saving a child from a burning building or discovering a new star. I was daydreaming at school one morning when my teacher said there would be a Father’s Day writing competition for the whole schoo1. “I hope we have a winner right here in my class.”

When I got home,I started to think about what to write. My father is an astronaut. No, I wouldn’t start like that.That was the way others saw him.How did I see my father? Hmm.

I saw him sitting with me in the dark when I had a terrible dream.I remembered how he hugged me for hours when my dog Spotty was killed by a car.Yes,these were the things I was going to write.To me,he wasn’t just a world—famous astronaut.He was my dad.

My parents and I went to school on Thursday night. There were so many people in the big hall! My dad looked at me, and I shrugged(耸肩).

The third prize was announced and it was not me. I was relieved(释然)and disappointed at the same time. The second prize was announced. It was me.

I went up to the stage and read what I had written,“My father’s son”. When I finished, the people stood up and cheered. I saw my father blowing his nose. Tears were running down my mother's face.  Dad cleared his throat and put his hand on my shoulder. “Son, this is the proudest moment of my life.’’

It was the proudest moment of my life, too. Maybe I’ll never be a great hero or win a Nobel Prize, but it was enough just to be my father’s son.
