The Value of an Hour
It was Thanksgiving morning. In the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey1the doorbell rang. I opened the front door and saw two small children in2clothes and thin little sandals(凉鞋), staying together at the door on the top step.
“Any old3, lady？” asked one of them.
I was4. I wanted to say “no” until my eyes were5their sandals, which were wet with heavy snow.
“6 and I'll make you a cup of hot cocoa.”
They walked7and sat down at the table. Their wet sandals left marks upon the8. I served them cocoa and bread with jam to fight9the freezing cold outside.10 I went back to the kitchen and started again on my household budget for Thanksgiving Day.
The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice，“Lady, are you11？”
I looked at my old sofa covers（沙发套）. The girl put her cup back in its saucer(托盘)12 and said, “Your cups match your saucers.” Her voice was13with a need that no amount of food could
supply. They left after that，14 their papers against the wind. They hadn't said “Thank you.” They didn't need to. They had15me that I had so much for which to be grateful. Plain blue china cups and saucers were16worth five pence. But they matched.
I tasted the potatoes and the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job—these17，too.
I moved the chairs back from the fire and18the living room. The muddy(沾上泥的)19 of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to20how rich I am.
