A few weeks ago, a friend from an unknown Smile Groups sent me $120 to do good things. Since then I have used the money in the US. It has helped families and strangers and generally raise a lot of smiles. They have warmed my heart, but none was so much as the gift I was able to give an hour ago.

I was in a charity shop, looking at the second-hand books. It happened that the bookshelves were next to the toy shelf. I noticed a group of poorly dressed women standing behind me. As they looked through the cloth shelf, a little girl about three years old came over to the shelf. Immediately her attention was caught by a toy pram(手推车). She spoke to her mother and she asked the shop assistant how much it cost. $3 was the answer.

The mum looked down at her child, perhaps thinking what she still had to buy and how much money she has left. Then she shook her head. The child did not behave (表现)as badly as some might. Being told “no” was not new for her but she could not keep the disappointment (失望的)from her face.

I had a total of $ 5 in my pocket. I touched the mother on the shoulder, put the money in her hand and said, “Buy her a doll, too”.

I did not wait to see the end. After all, it was not about being thanked. I walked out of the shop and into the sunshine.

The money the friend gave me was to help me find happiness of the world. Was there any better way, I wondered, to get so much happiness for so little money than to buy a little girl a toy and a doll to sit in it?
