Just to be clear, I still cannot watch the 9/11 footage. If they start showing part of it in a news story, I have to turn the channel. I found what happened to be incredibly emotionally devastating. There is zero chance I will ever forget the day.
I play MMO's. At the time of 9/11, I played an online game called Everquest. After I had to run from the coverage of the disaster, being totally unprepared for the sight of people jumping to their death to avoid the heat of the building and things of that nature, I logged into Everquest. There where people online in the game, who knew people who worked in the WTC, who knew people in New York, or who lived in New York, all doing largely what I was doing, getting away from the pain. I remember some of the things they where saying, and marveled at the pain and torment these people where feeling.
9/11 affected me deeply, and forever. I think that is true for almost every one, liberal or conservative, republican or democrat. I don't think we are in any danger of forgetting 9/11.
