Yesterday my son, daughter and I went to the grocery store. In front of us in line was a little girl with her mother. The little girl was asking her mother for a box of Smarties. The polite way she was asking almost broke the mother’s heart, “I’m sorry, Honey, but we have no money to buy it ”
My son was watching that dialogue. By the way, he had been raking(用耙子耙)leaves our garden to raise himself some money to buy a bike. As he watched the mother and daughter leave the store, he ran to the candy counter(柜台)and bought a box of Smarties with the money .
He turned to look at me and I just nodded. He ran out after the little girl and her mother and he gave them the box. He came back and told me what he told them. “Every kid should have a pack of Smarties because they can make you smart.”
I was so excited that I bought a pack of Smarties for my son. I told him that I was proud of him, and that was for his act of generosity(慷慨)because he gave his own Smarties to others  Quickly, he replied, “But you do nice things for people and you never get anything for it .”explained, “when you do something nice for someone, you shouldn’t expect to get anything, when you do get something you should be very thankful.”
【小题1】When the writer and her children went to the grocery store, they saw a little girl asking ____.

 Yesterday I was shopping for a few items(物品).With nothing to do at home, my son, who just left university, was ready to go together with me.
As I pushed the basket towards the register(收银机),I checked my items to see how many I had, thinking I might go to the Express Line(快速通道)where the sign said“Ten items or less”.
I started to go to that line and my son said,“Mon, you have twelve items!”I said,“You know, but they’re close.” He said,“Why are you in such a hurry to get home? You should go to the Regular Line because you have over ten items.”
Knowing he was right. I agreed and then pushed the basket to the next line. So I was waiting for my turn there and I was just removing my items from the basket to pay for them when a young man came up behind me in line with two items.
I just left the Express Line because I had too many and now I really wanted to get finished. Again, my son came up.“Mom, he has only two items and the Express Line is very long now. Won’t you just let him go first?”I agreed, and the young man smiled widely and thanked me several times.
It felt good to be with my son and have him remind me not to live a hurried life. Do what’s right and also be kind. I really take pride in him.
