| Towards the end of the baseball game, a controversial call was given. At full speed Paul Harvey slid home （本垒）and, thinking he had just ___1___ a game-changing run, he stood up only to face the words, "You're ___2___!" Angry, he threw off his helmet and ran over to explain to the ___3___ why the call was wrong. Before his ___4___ really got out of control, someone pulled him away, and he walked to the bench— ___5___. Long after the coaches, players, and fans had gone home, he realized the impact of his ___6___. Like most of us do when we are faced with the __7___ of our actions, he could have just let it go, reasoning, "Everybody ___8___ it." However, in the silence of his heart, he knew that just ___9___ everyone else does it, that doesn't make it all right. And so, long after his friends had gone home, he ___10___ that coach back up to the school-not to ___11___ his car. No, the boy tracked this man down so he could tell him face to face, "I'm sorry, Sir. It was all my___12___." It takes true courage to stand up to face the ___13___ we all make and say, "I was wrong. I'm sorry." What makes this ___14___ unique is that it wasn't meant for the world to ___15___, it was meant simply as a way to stay ___16___ to his own heart. The truth is at one time or another we have all been this boy —___17___ out in anger, saying hurtful things, and feeling ___18___ for doing so. But the real test comes later when we are ___19___ with the choice to say "sorry" or to walk away thinking, "Ah, they'll get over it." Maybe the "they" is a customer, a friend, or a child. Whoever it is, don't pass up the opportunity to get right with your own heart. The time for apology is now! Courage is a ___20___ of the heart. | ||||
