September 11th, 2001, was a dark day in American history. The terrorist attacks on the World Trade Center in New York City and the Pentagon in Washington D.C. claimed the lives of thousands of innocent people, and left the nation reeling with shock and grief. However, in the years that followed, the date has come to symbolize something more than tragedy and loss. September 11th has become a day to honor the courage and resilience of those who were affected by the attacks, and to celebrate the spirit of hope and unity that emerged in the wake of the tragedy.
