Once upon a time, Bill and his mommy went to the airport. Everywhere, Bill could see very big planes on the ground. He wondered how heavy these planes were, so he asked his mommy to weigh them.
"Mommy, how can we weigh these planes?", he asked.
His mommy smiled at him and said, "Sweetheart, we can't weigh these planes but we can see how compassionate everyone at the airport is."
Bill saw people helping each other with their luggage, and he saw the pilots being kind to the other people. He was amazed! 
"Is this how they weigh the planes mommy?", he asked.
His mommy smiled. "No, sweetheart. Compassion is something which can't be measured," she said. "We measure things like weight with scales, but we can't measure feelings in the same way." 
Bill thought about this for a moment and then he smiled. He wanted to be kind like the people at the airport, so he said to his mommy, "Let's be compassionate too!"
