     When a terrible earthquake hit, many people were killed and many houses fell down. After the earthquake, all

the newspapers reported many stories about some of the families who were in trouble.

     One Sunday, when I was reading a newspaper, a special picture touched me. It gave the clothing sizes of

each family member. I thought that this would be a good chance to teach my children to help those who were

less lucky than themselves. I said to my seven-year-old twins, Brad and Brett, and three-year-old Meghan. "We

have so much, and these poor people now have nothing. We'll share what we have with them.”

     I filled a box with foods and clothes. While I was doing this, I encouraged the boys to choose their toys and

donate some of their less favorite things. Meghan watched quietly as the boys took out their old toys and games

and put them together. Then she walked away. A few minutes later she came back with Lucy, her much-loved

doll. She put the doll on top of the other toys. "Oh, dear," I said. "You don't have to give Lucy. You love her so

much." Meghan said, "Lucy makes me happy, Mommy. Maybe she'll make another little girl happy, too." 

     I looked at Meghan for a long moment. She taught me a lesson. It's easy to give something that we don't

want any more, but harder to give what we cherish (珍爱), isn't it?
