If there is some occasion in last twenty years that changed face of the world it is 9/11 bombings for sure. World will never be the same. In eighties you could carry a gun to airplane today you cannot take a shampoo. But that is something completely different. No I want to speak to every single one of you who are patriotic or you just feel with USA. There is a website called pixslr.com and they will do with your profile photo something similar like Facebook did after Parris attacks. So just visit a page and you can have your profile photo with underlying American flag. Just visit and show that you feel with sadness of millions.
