Proudly reading my words, I glanced around the room, only to find my classmates with big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had worked on, hoping to hide myself. “What could be causing everyone to act this way?”

Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched for the name of this fellow, it became obvious that there were two people with the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice: flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quiet! How could I know that she meant that George Washington?

Obviously, my grade was terrible. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. At last, I worked very hard for the rest of the school year.

Ten months later, that chance came as I found myself sitting in the headmaster’s office with my grandfather, now having a completely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my chance to skip the sixth grade. Justice is sweet!
