     It was the old lady's eightieth birthday. She was sure Myra wouldn't forgot her mother's birthday,

even if she was busy. After all, eighty was a special birthday. Perhaps Myra might come. Even if Myra

did not come, she would send a present. The old lady was sure of that. Two spots of colour brightened

her cheeks. She was excited like a child.

    Mrs. Morrison had brought a card and a bunch of flowers when she came to do the breakfast. Mrs.

Grant downstairs had made a cake. Johnnie, the little boy next door, was now up with her with a packet

of sweets.

    "I guess you'll get lots and lots of presents, " he said. "I did last week when I was six."

    What would she like? A pair of slippers, perhaps. A blue new cardigan. Or a table lamp. Or a little

clock, with clear black numbers. So many lovely things.

    She stood by the window, watching. The postman turned round the corner on his bicycle. Her heart

beat fast. Johnnie had seen him too and ran to the gate.

    "Granny, granny, " Johnnie returned. "I've got your post!"

    He gave her four envelopes. Three were from old friends. The fourth was in Myra's writing.

    "No parcel(包裹), Johnnie?"

    "No, granny."

     Almost reluctantly, she tore the fourth envelope open. Folded in the card was a check. Written on the

card was a message: Happy Birthday-Buy yourself something nice with the check, Myra and Harold.

     The six-figure check fell to the floor like a bird with a broken wing. Slowly the old lady bent to pick it

 up. Her present, her lovely present. With trembling fingers she tore it into little bits.
