I remember September 11, 2001 very well. I was in the DC metro area at the time, and for several hours that day we panicked that my father, who had been at the National Mall conducting an interview, might have been killed when early reports said a plane had crashed on the Mall. Later, it was obviously confirmed that no such thing had happened, but in concert with cell phones not working, and the ever more horrific news of the day, it was not a fun day for my family. I remember thinking quickly to email all our family abroad - and lying to them - letting them know that we were all ok.
Fortunately for us, Dad did what all good journalists do and he followed the story and had spent the day reporting from the State Department. When he came home that night, we were so happy but I could tell he was so sad about everything that had happened. He came to America in 1969 to get away from the conflict in the Middle East, and here we were living through more stupid warfare bullshit all over again.
All that being said, I don't think saying that "I don't want this wound to heal" is a very healthy approach to this matter. It is entirely possible to remember, to honor and to memorialize the events, heroes and victims of that awful day without forgetting but still be able to move on.
I remember a year later on campus, when we had the memorial service on 9/11/2002 and how we had interlopers restrained by campus security for shouting out that 9/11 had happened because Jesus didn't love us anymore; I also vividly recall the snipers on the roofs of the surrounding buildings during said memorial.
I remember the black plumes of smoke spiraling away from the Pentagon for days after the attacks and how you could see it from just about anywhere in town.
I remember being angry.
I remember the sad rush of everyone to blame the Middle East. I remember seeing AIM away messages and profiles reading "I HOPE TOMORROW THE MIDDLE EAST IS A BURNING, SMOKING CRATER" and the overtly patriotic "THESE COLORS DON'T RUN" in pixelated red, white and blue.
I remember our film theory professor telling us we could have the afternoon free - "Somehow, I don't think watching and discussing "Battleship Potemkin" would be ideal right now."
I remember a fiction writing class the next day, where my professor declared - "There's good and evil in literature and in entertainment. We know there's good in the world. And we knew already there was evil in the world, but now we know it again."
I remember the conversation I had with my little sister in the days after September 11. She was only 12 at the time, and the look on her face when she told me - "This is my generation's disaster." When I asked her what she meant by that, she told me "You were a kid when the Challenger exploded. Mom and Dad grew up learning about Hiroshima and Nagasaki and Pearl Harbor and D-Day. This is the tragedy everyone my age will remember for their entire lives." She and her friends would later walk up and down our street with candles, singing the Star-Spangled Banner with anyone who would join them.
I remember going back to work at the university admissions office and fielding calls from parents and students, everyone worried about their kids and their standing at the university 20 minutes from DC. I remember soldiers withdrawing their admission to deploy or join up. I remember international students withdrawing admission because they were afraid of how they would be treated following such a horrific attack.
I remember skipping French class because I didn't want to take an exam that day. I remember schools in Bumblefuck, Iowa were cancelling classes for the next week yet here we were, 20 minutes from where one of the attacks had happened and we were still in class.
I remember the new "News Center" in our student union, a bunch of monitors set up next to the library and across from the food court. It had been installed that summer and for the first week of classes nobody cared. It was just a big black wall with monitors set to various news stations (and at times, daytime soap operas.

) I remember getting to campus on September 11th and seeing that alcove jam packed with people watching CSPAN, CNN, Fox News, and MSNBC.
I remember the day of the attack, hugging my friend Emily as she cried watching the towers come down on a shitty old TV with bad reception. I remember being trained on how to field a call of a bomb threat came in. I remember meeting the Dean of admissions that day, based on how he'd introduced myself with his first name, thinking for months that he was just some other counselor I could call by his first name after he'd ordered pizzas for the office.
So no, I don't think 9/11 is something that people will ever forget about. We may move on, but we will never forget.
