     It was Saturday. As always, it was a busy one, for "Six days shall you labor and do all your work"

was taken seriously back then. Outside, Father and Mr Patrick next door were busy chopping firewood.

Inside their own houses, Mother and Mrs. Patrick were engaged in spring cleaning.

Somehow the boys had slipped away to the back lot with their kites.Now, even at the risk of having

Brother caught to beat carpets, they had sent him to the kitchen for more string(线). It seemed there

was no limit to the heights to which kites would fly today.

     My mother looked at the sitting room, its furniture disordered for a thorough sweeping. Again she

cast a look toward the window. "Come on, girls! Let's take string to the boys and watch them fly the

kites a minute."

     On the way we met Mrs. Patrick, laughing guiltily as if she were doing something wrong, together

with her girls.

     There never was such a day for flying kites! We played all our fresh string into the boys' kites and

they went up higher and higher. We could hardly distinguish the orangecolored spots of the kites. Now

and then we slowly pulled one kite back, watching it dancing up and down in the wind, and finally

bringing it down to earth, just for the joy of sending it up again.

     Even our fathers dropped their tools and joined us. Our mothers took their turn, laughing like

schoolgirls. I think we were all beside ourselves. Parents forgot their duty and their dignity; children

forgot their everyday fights and little jealousies. "Perhaps it's like this in the kingdom of heaven," I

thought confusedly.

     It was growing dark before we all walked sleepily back to the houses. I suppose we had some sort

of supper. I suppose there must have been a surface tidyingup, for the house on Sunday looked clean

and orderly enough. The strange thing was, we didn't mention that day afterward. I felt a little

embarrassed. Surely none of the others had been as excited as I. I locked the memory up in that

deepest part of me where we keep "the things that cannot be and yet they are".

     The years went on, then one day I was hurrying about my kitchen in a city apartment, trying to get

some work out of the way while my threeyearold insistently cried her desire to "go park, see duck."

     "I can't go!" I said. "I have this and this to do, and when I'm through I'll be too tired to walk that far."

     My mother, who was visiting us, looked up from the peas she was shelling."It's a wonderful day,"she

offered, "really warm, yet there's a fine breeze. Do you remember that day we flew kites?"

     I stopped in my dash between stove and sink. The locked door flew open and with it a rush of

memories. "Come on," I told my little girl. "You're right, it's too good a day to miss."

     Another decade passed. We were in the aftermath (余波)of a great war. All evening we had been

asking our returned soldier, the youngest Patrick Boy, about his experiences as a prisoner of war. He

had talked freely, but now for a long time he had been silent. What was he thinking of-what dark and

horrible things?

      "Say!" A smile slipped out from his lips."Do you remember -no, of course you wouldn't. It probably

didn't make the impression on you as it did on me."

     I hardly dared speak."Remember what?"

     "I used to think of that day a lot in POW camp (战俘营), when things weren't too good. Do you

remember the day we flew the kites?"
