On November 9, 1989, I was at the right place at the right time in history. My family was in West Berlin, Germany. We were visiting my grandparents. For nearly thirty years, people in East Berlin and West Berlin had been separated by two different governments and one big wall. The 28-foot wall had been put up to keep people in East Berlin from escaping to West Berlin. People in East Berlin did not have the same freedoms as those in West Berlin.

On that November night, though, the East Berlin government allowed the wall to come down. Berliners were reunited. Dad took us to the wall. Hundreds of people were there, shouting and cheering. Music was coming from all directions. Some of the people climbed on the wall and began hammering at pieces of it. A man was helped down from the wall. When the man saw me, he reached into his pocket and handed me a piece of the wall about the size of a marble.
In the days and weeks after that night, bulldozers and cranes tore down large chunks of the wall until it was gone. To this day, whenever I look at that small piece of wall, I remember that November night. It was a day of great celebration.
