On the way back，Mrs.White saw an old woman sitting in a chair at the old people's home.They stopped the car and Mrs.White walked to the old woman and put the flowers in her hands.The old woman thanked her again and again.
When Mrs.White came back to the car，her children asked her， "Why did you give our flowers to her？"
Their mother said， "It's Mother's Day，and she has no children.I have all of you，and I still have my mother.Those flowers will mean （ 意味着 ） a lot to her."
