I opened my door to two little girls.I had met Alyssa,six,two weeks before.Since then,she'd waved to me every time she passed my house.

"Hello.Grandma Bonnie!"Alyssa said."This is my little sister,Ariana.She's three."To her very nervous sister,"It's OK,honey.You'll like her."The three-year-old held a "bouquet"（花束）in one hand,and the other gripped（紧握）a tiny notebook and a huge broken crayon."Go on,"her big sister urged,"tell her."

Ariana looked at me seriously."I want to help raise money for my preschool,"she said,holding out her flowers. "So I'm selling these for one dollar a bunch."

I had a hard time hiding my smile.The bouquet consisted of seven oxalis（醡浆草）flowers.Oxalis is a weed almost impossible to get rid of.Obviously Ariana had pulled these flowers out from her own yard or a neighbor's.

Her big sister smiled,"Aren't they lovely,Grandma Bonnie?And they only cost a dollar for the whole bunch.It's all for Ariana's preschool."The girls' plan did amuse me."All right," I agreed,"one dollar coming up."

Alyssa put the bill in her sister's skirt pocket.Then Ariana handed me my purchase."Uh,"I suggested,"why don't you just keep the flowers and the money? Then you could sell the flowers to someone else."Both girls stared at me, horrified."Oh,no,"Ariana cried."We picked them just for you.See,they're beautiful!"

And so they were.A week later,the flowers were twice as many as when my little neighbor handed them to me.What a bargain!

I had called these tiny plants "weeds"—disgusting,worthless things with no right to exist.But in their innocent hearts,those two little girls saw them as a precious creation to treasure and share out of loving hearts to brighten the day of a lonely old "Grandma".
