题目内容：

I live in the center of the city and there is a large parking lot full of parking spots nearby．Rain is a rare occurrence in LA，so cars easily collect pollutants and dust．Together with my friends，I decided it should be a kind gesture to surprise the owners with a car wash．So we bought car washing supplies and brought out all the bath towels we could find．With all the supplies in hand，we were able to convince another roommate to help out as well and we began watering down the cars．

Every once in a while，someone would come by and asked us seemingly stupid men，“Who told you to wash the cars?”or，even better，“who paid you to wash their cars?”We explained we just wanted to do something kind．But our response was often me with an even more confused look．

As the afternoon went on，some other friends that came by understood our goal of the spontaneous event and started helping out with some of the duties．First one friend then two，and by the time we had cleaned the entire lot，we had an entire car washing crew with independent individually assigned tasks and duties．

I wasn't cleaning cars to be able to afford a new phone．I was cleaning cars simply because I wanted to offer the car owners kindness．There was no equipment to weigh our value created．We couldn’t measure our success in dollars earned over the time spent washing cars when we could have been earning twice as much at work．

I now realize，first hand，that there is a special energy created when you choose to think bigger than yourself and act in service of others and maybe，like me，you’11 find it’s actually the greatest gift you’ you’ll ever get．
