How did american citizens respond to the september 11 2001 attacks

Shortly after the Twin Towers fell on September 11, 2001, the nation began to mourn, and around the country Americans began to commemorate the victims and demonstrate their patriotism. Some flew the American flag from their front porches and car antennas. Others pinned it to their lapels or wore it on t-shirts. Sports teams postponed games. Celebrities organized benefit concerts and performances. People attended impromptu candlelight vigils and participated in moments of silence. They gathered in common places, like Chicago’s Daley Plaza, Honolulu’s Waikiki Beach and especially New York City’s Union Square Park, to post tributes to the dead and to share their grief with others. They all felt differently about what to do in response, but everybody seemed to agree that they had to be together no matter what happened. So they had a little bit of hope in togetherness.”
