On the day the Twin Towers collapsed we were all in shock. We did not know much about the Taliban or Al-Qaeda. The idea that someone, anyone, would actually carry out a terrorist attack of this magnitude on the US homeland was foreign to the minds of most Americans. On that day, we went about our business doing the things that made our lives typically American. Businessmen were engaged in business, tourist went sight-seeing, and the labor force that cared for the infrastructure performed their menial jobs. Within the midst of it all extended two magnificent engineering and architectural accomplishments - the Twin Towers. In a matter of minutes they were gone. We were left with the horror of watching them fall. And we were left with the memory of that very moment. Forever, our lives will carry the memory of where we were when the Towers fell.
