When I was a boy, I was always happy to see those little brown coins. After years I was still very happy to pick up pennies on the ground, I usually saved them up. I usually bought a pack of gum(口香糖) or a bag of chips when it was enough. After growing up, I heard a story about coins. It was said that our loved people sometimes would leave pennies on the ground in front of us. People wanted to show us that we were loved and watched over kindly. I never doubted that story even as an adult. It is difficult for me to find a lot of money on the ground, but pennies are there all the time. Maybe that is why I still enjoy seeing them and picking them up, no matter how dirty or old they are.

A few months ago, I was walking to the local post office to mail a letter. As I entered the room, I saw not one, not two, but four pennies shining in the sunlight. I smiled and picked them up. I kept them in my hands as I walked in the post office. “Four is OK,” the post worker said to a lady. The lady began searching her purse, turning it inside out twice in vain. Her face went red. I understood what had happened. I laughed to myself for this surprising moment. I placed my pennies on the desk before her. The smile I got in return was worth a thousand dollars.

The coins weren’t so valuable to me, but they did matter to her. I just performed a little kindness. I was happy.
