I don’t remember when it first started annoying me — her hands pushing my hair that way. But it    36    annoy me, for    37   felt work-worn and rough against my young skin.    38   , one night, I shouted out at her, “Don’t do that anymore — your hands are too rough!” She didn’t say anything in    39  . But never again did my mother close out my day with that familiar    40    of her love. Lying awake long afterward, my words stuck to me. But pride kept my conscience back, and I didn’t tell her I was    41  .

Time after time, with the passing years, my thoughts    42    to that night. By then I missed my mother’s hands, missed her goodnight kiss upon my forehead. Sometimes the incident seemed very    43  , sometimes far away. But always it hid in the back of my    44   .

Well, the years have passed, and I’m not a little girl any more. Mom is    45    her mid-seventies and those hands I once thought to be so rough are    46   doing things for me and my family. She cooks the best fried chicken in the world, gets stains out of blue jeans and still    47    on dishing out ice cream at any hour of the day or night. Through the years, my mother’s hands have put in countless hours of labor.

Now, my own children are grown and gone. Mom no longer has Dad, and on special occasions, I find myself drawn next door to    48    the night with her. So it was late on Thanksgiving Eve, as I slept in the bedroom of my    49  , a familiar hand hesitantly stole    50    my face to brush the hair from my forehead. Then a kiss, ever so gently, touched my eyebrow.

In my memory, for the thousandth time, I recalled the night, when my young voice    51   , “Don’t do that anymore — your hands are too rough!” Catching Mom’s hand in hand, I spoke out how sorry I was    52   that night. I thought she’d remember,    53    I did. But Mom didn’t know what I was talking about. She had forgotten — and forgiven — long ago.

That night, I fell asleep with a new    54    for my gentle mother and her    55   hands.
