| Night after night, she came to wrap me in, even long after my childhood years. Following her longstanding custom, she'd lean down and push my long hair out of the way, then 1 my forehead. I don't remember when it first started 2 me-her hands pushing my hair that way. But it did annoy me, for they felt work-worn and rough 3 my young skin. Finally, one night, I 4 her, "Don't do that anymore -your hands are rough!" She didn't say 5 in reply. But 6 again did my mother close out my day with that familiar 7 of her love. Time after time, with the passing years, my 8 returned to that night. By then I missed my mother's hands; 9 her goodnight kiss on my forehead. Sometimes the incident seemed very 10 ,sometimes far away. But always it hid, in the back of my mind. Well, the years have passed, and I'm not a little girl anymore. Mom is in her mid seventies, and those 11 I once thought to be so rough are still doing things for me and my family. She's been our doctor, 12 a medicine box to calm a young girl's stomach. She cooks the best fried chicken in the world...gets 13 out of blue jeans that I never could wash out... Now, my own children are grown and gone. 14 , in my memory, for the thousandth time,I 15 the night when my young voice complained, "Don't do that any more-your hands are rough!" Catching Mom's hand in hand, I blurted out (冲口而出) how 16 I was for that night. I thought she'd remember, 17 I did. But Mom didn't know what I was talking about. She had forgotten-and 18 long ago. That night, I fell asleep with a new appreciation for my 19 mother and her caring hands. And the 20 that I had carried around for so long was nowhere to be found. | ||||
