It was a very dark day, just tragic.
The repercussions from it are far from over.
I feel very bad for my many non American friends who live in America. Our government has made things very difficult for them even through they are hard working honest folks and had nothing to do 9/11 and truly do love America.
When I was a child I watched them build the towers and ate at the restaurant that was at the top after they were completed. I remember getting motion sickness in them before they added stabilizers to them. I feel a great loss seeing the NY skyline without them.
I feel anger at those responsible, but I also understand how our government has caused resentment in some countries.
All in all it is just a big tragic fucking mess.
