On Sundays my father always wore that gray apron(围裙)—the one with the race cars all over it. The ritual (老规矩) began.       breakfast when Dad always announced, “Go ahead everyone. I’ll       the dishes!” For the next hour Dad did the dishes, singing ballads (歌谣) like “I Had a Hat When I Came in.” and “Who Put the Chow in Mrs. Marphy’s Chowder?”
I suppose it was        for a boy’s father to wear an apron—even one with race cars—        I never thought much of it until the day that Dad broke with tradition. It was the last Sunday in August. As we        home slowly from church together, my father seemed very       . “Tommy,” he said letting my name roll off his       . “There comes a time in every boy’s        when he must take on responsibilities. It’s time you        a greater role in the family. From now on, I want you to        the dishes on Sunday morning, so your mother and I can work the crossword puzzle (纵横字谜) together.”
“The dishes!?” I        in surprise.
“Anything wrong with taking over the dishes, son?” father said.
I started to say something about a man’s        or woman’s work, but I knew immediately that my protests (抗议) would be        .
I didn’t taste a bit of       that morning. Dad seemed joyful as he described an American game.[]
At the end of the meal, my father        , “Let’s go to read the paper, honey.” “Aren’t you doing the dishes?” my 51 asked surprisedly. Father smiled and said, “your oldest son has        to fill the position.”
“I want you to have this apron on, Tommy. It’ll keep your clothes from getting        .” And before I could go against it, he had put the thing on me. “Thanks, Son. Your mother and I        this.”
With that he disappeared into the Sunday paper. I looked        at the dishes. I could see my dad reaching for the dishes. He was always happy to help the family. My anger soon flew off and I began to sing.
