9/11 should be a national holiday for everyone to remember all of the people who died when towers fell in 2001

in 2001 the twin towers fell in New York and part of the Pentagon was destroyed, in schools around fairfax county Virginia the teachers only talk about the incident and have a small moment of silence instead of watching the film of the towers falling in history or civics. But since there are many people who mourn the loss it would be more efficient if the day was a national holiday
