I was doing some last-minute Christmas shopping in a toy store. A nicely dressed little girl was looking through the teddy bears beside her father 38 she saw a little boy walk in and stop in front of the Pokémon toys. His jacket was obviously too small. He had money in his hand. 39 , it looked no more than five dollars at most. He was with his father as well, and 40 picking up the Pokémon video games. Each time he showed one to his father, his father 41 his head, “No”. Rather 42 , the boy gave up the video games and chose a book of stickers 43 . After they walked away, the little girl ran over to the Pokémon video games. She excitedly picked up one 44 on top of the others, and hurried down toward the check-out. I picked up my purchases(购买物) and 45 the girl and her father. Then, much to the little girl’s 46 , the little boy and his father got in line behind her and me. After the video was paid for and bagged, the little girl 47 it back to the cashier(收银员) and 48 something to her. The cashier smiled and put the 49 under the counter(柜台). I was putting things in my bag when the little boy came up to the cashier. The cashier said, “Congratulations. You’re my hundredth customer today, and you win a prize!” and she handed the boy the Pokémon game. The boy could only 50 in disbelief. It was, he said, exactly what he had wanted! The little girl and her father had been standing at the doorway, and I saw the biggest and prettiest smile on that little girl I have ever seen in my life. I suddenly understood that the world is not 51 into the strong who care and the 52 who are cared for. We must each in turn care and be cared.
