The Value of an Hour

It was Thanksgiving morning. In the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey     the doorbell rang. I opened the front door and saw two small children in     clothes and thin little sandals(凉鞋), staying together at the door on the top step.

“Any old     , lady？” asked one of them.

I was     . I wanted to say “no” until my eyes were     their sandals, which were wet with heavy snow.

“     and I’ll make you a cup of hot cocoa.”

They walked     and sat down at the table. Their wet sandals left marks upon the     . I served them cocoa and bread with jam to fight     the freezing cold outside.     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 you     ？”

I looked at my old sofa covers（沙发套）. The girl put her cup back in its saucer(托盘)     and said, “Your cups match your saucers.” Her voice was     with a need that no amount of food could

supply. They left after that，     their papers against the wind. They hadn’t said “Thank you.” They didn’t need to. They had     me that I had so much for which to be grateful. Plain blue china cups and saucers were     worth 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—these     ，too.

I moved the chairs back from the fire and     the living room. The muddy(沾上泥的)     of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to     how rich I am.
