| Last weekend, my kids along with few other kids from the neighborhood volunteered to help me wash my car. My 10yearold daughter came up with the idea of __1 _ other people's cars as well. It was pretty __2__ outside and I had no plans to __3__ being in the bright sun. She __4__ wanted to give lemonade(柠檬汽水)to passersby for free. I had seen little kids __5__ and sell fresh lemonade for a small cost but not free. Although I felt __6__, I decided to help her. __7__ she asked me, "What if we __8__ this a smile car wash?" I couldn't hold back my tears and 9 her and the other kids to go outside the house and come up with 10 ideas. While I kept myself busy in drying the car, the gang walked up to me with a(n) 11 with beautiful images of smiles. They had "Free Car Wash" written on it and the 12 of their exercise was "smile". It was pretty neat to see a team of kids ranging 5－11 years with the 13 to do something for others. All that seemed 14 and came right from their heart. Nothing seemed to 15 to them: their playtime, the heat outside-they just wanted to 16 others and do something nice in the community! I helped them make some fresh lemonade and brought out some additional 17 to help clean cars. Passersby were 18 and one even shouted back to them saying "God Bless You, my kids…" One of them even tried giving them 5 dollars, which they refused. A pretty heartwarming 19 ! I feel blessed by being 20 by such wonderful and loving souls. | ||||
