单选题根据以下材料，回答题
I've loved my mother's desk since I was just tall enough to see above the top of it as mother sat writing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I de-cided that the act of writing must be the more wonderful thing in the world. Years later, during her final illness, mother kept different things for my sister and brother."But the desk," she'd said a-gain, "it's 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 fami-ly. 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 disap-pointment, then little interest and, 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 try-ing to make her into someone she was not.
Now the present of her desk told, 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 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.
The writer began to love her mother's desk

A． after mother died
B． before she became a writer
C． when she was a child
D． when mother gave it to her
