Never forget.
..and never forgive. I was very fortunate on September 11th - my mother might have been right by the WTC for a language lesson. It was a stroke of luck that she wasn't. I will never forgive those who might have killed her had my luck been off that day. I will never forget who they are, who supported them, who cheered them on, or who even said the attack was justified. I will never forgive them either.
