9/11 is one of those days we remember. Not the day alone, but also other subsequent 9/11s. Of course, I remember the day like it was yesterday. My father yelled down the stairs to the basement (I was homeschooled). He had just gotten off AOL Instant Messenger with a friend who told him that a plane had crashed into one of the World Trade Towers. At that point, it was thought that it was accidental.
