stranger and I. Then we went   2   our way after saying good-bye.
     But at home a   3   story is told. Later that day, when I   4   supper in the kitchen, my daughter suddenly
stood behind me very   5   . When I turned back, I   6   knocked her down."Don't be in my   7   !" I shouted
angrily. She walked away with her little heart   8   . On the kitchen floor later, I found some flowers by the
door.
     That night, while I lay   9   in bed, a voice in my deep heart said,"While   10   with a stranger, you are so
polite, but with the children you love, you are so easily   11   . Why are there some flowers by the door? Those
are the flowers she brought for you. She   12   them herself, pink, yellow and your favorite blue. She stood
quietly in order to give you a   13   , and you never saw the   14   in her eyes."
     By this time, I felt very   15   and now my tears began to fall. I quietly went and knelt (跪下) by her   16  ,
"Wake up, little girl, wake up," I said, "Are these the flowers you picked for me?" She smiled, "Yes, because I
knew you'd like them, especially the  17   ." I said, "Daughter, I'm sorry for the way I acted today; I   18   have
shouted at you that way."
     She said,"Oh, Mom, that's okay. I love you  19   ." I hugged her and said, "Daughter, I love you too, and I
do like the flowers."
