     Last weekends, my kids along with a few other kids from the neighborhood volunteered to help me wash
my car. My 10-year-old 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   be ing in the bright sun. She   4   wanted to give lemonade (柠檬汽水) to
passers-by 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. Noth ing 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.
Passers-by were   18   and one even shouted back to them saying"God bless you, my kids..."One of them even
tried giving them a 5 dollars, which they refused. A pretty heartwarming   19   !
     I feel blessed by being   20   by such wonderful and loving souls.
