A successful man was driving his new car down a street. He saw a kid was throwing stones at the cars, and then he slowed down. But as his car passed, no children appeared. Instead, a stone hit the car's side door! He drove his car back to the place where the stone had been thrown. The angry man jumped out of his car, caught the kid and shouted, "What was that all about? That's a new car and that stone you threw is going to cost a lot of money. Why did you do it?"
The young boy was apologetic. "Please sir... please, I'm sorry... I didn't know what else I could do. I threw the stone because no one stopped..." With tears in his eyes, the boy pointed to another boy. "It's my brother," he said. "He fell out of his wheelchair (轮椅) and I can't lift him up."
The man lifted the boy back into the wheelchair in a hurry. Luckily, the boy wasn't hurt.
"Thank you very much," the child said to the stranger.
The little boy pushed the wheelchair toward their home. It was a long, slow walk back to the car. The damage was very noticeable (明显的), but the man never repaired the side door. He kept the dent (凹痕) there to remind him of this message: Don't go through life so fast that someone has to throw a stone at you to get your attention!
