Night after night, she came to tuck me in (给…掖被子), even long after my childhood years. Following her long-standing custom, she’d        and push my long hair out of the way, then kiss  my forehead.
I don’t remember when it first started        me----her hands pushing my hair that way. But it did annoy me,       they felt work-worn and rough against my young skin.        , one night, I shouted at her, “Don’t do that anymore ----your hands are too       !” She didn’t say anything in reply. But never again did my mother close out my day with that        expression of her love.
Time after time, with the passing years, my thoughts        to that night. By then I missed my mother’s         , missed her goodnight kiss on my forehead. Sometimes the incident        very close, sometimes far away. But always it existed in the back of my        .
Well, many years have passed, but mother’s rough hands are still doing things for me and my family. She’s been our doctor,        into a medicine cupboard for the medicine to         us children of our pain. She makes the best food in the world and always keeps our clothes clean.
Now, my own children are grown and gone. Mom no longer has Dad, and on special        , I find myself drawn next door to spend the night with her. So it was late on Thanksgiving Eve, as I slept in the bedroom of my youth, a familiar hand        ran across my face to brush the hair from my forehead. Then a kiss, ever so gently,        my forehead.
In my memory, for the thousandth time, I        the night my young voice        , “Don't’ do that anymore----your hands are too rough!”        Mom’s hand in my hand, I blurted out how sorry I was for that night. I thought she’d remember, as I did. But Mom didn’t know what I was talking about. She had forgotten ---and       ---long ago.
That night, I fell asleep with new appreciation for my gentle mother and her caring hands. And the        that I had carried around for so long was nowhere to be found.
