     I've loved my mother's desk since I was just tall enough to see above the top of it as Mother sat doing

letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing

must be the most wonderful thing in the world.

     Years later, during her final illness, Mother kept different things for my sister and brother. "But the desk",

she said, "is for Elizabeth".

     I never saw her angry, never saw her cry. I knew she loved me, she showed it in action. But as a young

girl, I wanted heart-to-heart talks between mother and daughter.

     They never happened. And a gulf opened between us. I was "too emotional". But she lived "on the surface".

     As years passed, I had my own family. I loved my mother and thanked her for our happy family. I wrote

to her in careful words and asked her to let me know in any way she chose that she did forgive me.

     I posted the letter and waited for her answer. None came.

     My hope turned to disappointment, then little interest, finally, peace-it seemed that nothing happened. I

couldn't be sure that the letter had even got to Mother. I only knew that I had written it, and I could stop trying

to make her into someone she was not.

     Now the present of her desk told me, as she'd never been able to, that she was pleased that writing was my

chosen work, I cleaned the desk carefully and found some papers inside-a photo of my father and a one-page

letter, folded (被折叠) and refolded many times.

     Give me an answer, my letter asks, in any way you choose, Mother, you always chose the act that speaks

louder than words.
