Once upon a time...
there was a man walking on the beach, as he walked along the shore he saw a lady moving like a dancer.
He smiled to himself as he walked to catch up.
As he got closer, he noticed that the lady was not dancing, she was reaching down, picking up small objects and throwing them into the ocean.
He came closer and said:
'May I ask, what are you doing?"
The lady looked up and replied:
"Throwing starfish into the ocean.
'Why?' he asked.
The lady replied:
"The sun is up and the tide is going out. If I don't throw them in, they'll die."
"But" he said, "don't you realize that there are miles and miles of beach, and there are starfish all along every mile? You can't possibly make a difference!"
At this, the lady bent down, picked up another starfish, an: threw it into the ocean. As it met the water, she looked at the man and said,
"It made a difference to that one."
