The other day I was sitting in the car, waiting, at the credit union. I was cleaning out my coat pocket and found a penny inside. I opened the car door and dropped it to the pavement, wondering if anyone would ever pick it up.
A few minutes later, a family parked next to me. Mom, Dad, and two kids got out. A boy about 7 or 8 years old yelled, "Hey Dad! Look! I found a penny!". He scooped it up and skipped down the sidewalk with it.
Even if it doesn't bring him good luck, it brought him a small bit of happiness. And gave me some too.
