3．A few days ago，I ran into a stranger as he passed by．I said sorry to him．And we were very polite．Then we went on our way after saying goodbye．
Later in the kitchen at home，as I cooked our meal，my daughter Betty walked up to me．When I turned around，I nearly knocked her down．"Get out of the way!"I shouted angrily．She ran away，crying．
That night，when I lay in bed，my husband said to me，"You were so rude to Betty．Go and look around on the kitchen floor，and you'll find some flowers there．Betty brought those for you．She picked them herself pink，yellow，and your favorite blue．"
When I heard this，I thought deeply．"While meeting with a stranger，I was calm and polite，but with my daughter，I was not patient．"I felt sad and tears began to fall．
I quietly went to Betty's bed．"Wake up，my dear!"I said，"Are these the flowers you picked for me？"She smiled，"I found them by the tree．I knew you'd like them，especially the blue．"I said，"I am so sorry that I treated you that way today．"And she whispered（悄声说），"Mommy，that's okay．I still love you anyway．"I kissed her and said，"I love you too and I do love the flowers．"
That day Betty gave me a lesson on how to get along with each other in the family．I spent much time on work before and  didn't realize how important family life was．I decided to do better in the future．
