My two little daughters and I usually go out and help others on Thankful Thursday. Last Thursday we were going to buy lunch for the beggars（乞丐）in the street. Then we went to the nearest McDonald’s（麦当劳）.
I ordered 15lunches from it and drove my car to hand them out.
We gave the lunches to the beggars. they were excited. We were happy to see that.
Then we noticed a small, old woman, asking for pocket money. We gave her our last lunch bag. Before we got into the car, she started to speak to us, "No one has ever done anything like this for me before, "she said with a smile. "Well, I’m glad that we were the first, “I answered. "So, when will you eat your lunch," I asked.
She just looked at me with her big, tired brown eyes and said, "OH, dear, I'm not going to eat this lunch. You see, I have a little girl of my own .I usually can’t buy her favorite food, but today she will be so happy! "
I don't know if the kids noticed the tears in my eyes. I have asked many times whether our Actions of Kindness were too small to change anything. Yet at that moment, I realized the truth of words: "We cannot do great things —only small things with great love."
