     My grandmother's eightieth birthday was approaching and I was at a loss as to what to give her. She
had recently moved into a nursing home and didn't have room for  1   things. She insisted that she didn't
need a thing.
      2  , I came up with an idea. In her   3   card, I sent her a gift certificate (礼券) for "A letter a   4   for
the next year!" It was a big   5  . I knew that she'd love to   6   what was going on in my life.
     The letter gift certificate was a big   7   . She got fifty-two letters that first year. Some were   8   and
filled with homesickness. Others were short and newsy. More than once what she   9   was just a funny
card with a few short  10  . All showed her that I was thinking of her regularly.
       11   her next birthday came around, she asked for another letter gift certificate.   12  , that's also
what she wanted next eight birthdays.
     For nine years I wrote her. She was rarely able to   13   back. I flew home annually to   14   and soon
realized that the entire nursing home staff knew all the details of my 15  , as more and more often they
were  16   the letters to her.
     My   17   letter arrived the day after her death. I felt I had given her the best gift I could. What I hadn't counted on (指望) was how her gift would come full circle to me.
     Months later, while   18   her things, my dad found a box full of letters from me. Those letters were
filled with moments and pictures I had completely forgotten. She   19   those memories for me in my letters. Sometimes our gifts to others come back to us in   20   ways.
