One of my former students worked for United Airlines, and was on the team sent by UA to help families of the 9/11 victims after the tragedy. He met a girl from American Airlines working on their team doing basically the same thing. (As most people know/recall, UA and AA each lost two planes, hundreds of passengers, and dozens of employees that day.) Anyway, they ended up dating and eventually got married. The wedding date they chose was 9/11 the following year, the idea being that they wanted the date September 11 to be remembered in a positive way, not a negative way. True story.
