"Never  forget" is a mantra easier said than done. Because the world just marches on, doesn't it? Our lives just keep happening. Unless we purposefully carve out moments to remember important things, we won't. It's just the way we are. The events of September 11th  were markedly terrible for the history of our nation and the world. The  largest foreign attack on U.S. soil? Terrorism had crossed the seas.
       Here's what I remember of that day:
        I began my teaching career on September 10th, 2001. My first day  teaching I had 7th, 9th, and 11th grade English classes, a 9th grade  Bible class, a study hall, and some other class I can't remember. That  first day was exhausting and overwhelming, especially for a 22-year-old  kid who didn't even have his teaching credential yet. Heck, I was only 4  years older than a couple of my students! I went to bed that night,  zonked out, then was awakened the next morning to a rude reality.
        At that time, I was not yet engaged to my now-wife and was still living  at home. I remember the knock at my bedroom door at around 5am, my  father opening my door, and him saying, 
       "Hey, Son, I know you're sleepy, but I think you should come see this."
       I interrogated him a bit (because doggonit, I was not ready to slither out of bed yet), and he convinced me to come see for myself.
        I sprawled groggily on the couch and stared at the television. A building I'd  never been aware of before was on fire. That morning, I would learn  about the World Trade Center in New York, that there were two towers,  and that they were an important center of trade.
       We, like  much of America, sat there watching the building smoke and burn,  learning about the airplane and the ideas behind it, as a second plane  crashed into the other tower.
       We were stunned. I called my  sleep-coma'd girlfriend (now wife) and said, "I think something  important is happening. You're going to want to wake up and turn on the  T.V."
       I and my dad and my girlfriend over the phone sat  there processing and panicking a little and prognosticating about future  attacks.
       Dad said we still had to get ready to go to school. "The world  isn't going to just stop because of this. I've gotta go be principal,  and you've gotta go teach."
       So I went to my classroom, and  students arrived, and the day was a blur of learning mixed with new and  scary discussions, and occasionally we were interrupted by someone  making an announcement of the Pentagon getting attacked and Flight 93  going down in a field. We prayed. We learned. We went on.
       And here we are, 14 years later, living in a totally different world than existed the day I started teaching.
       It's safer ... and more dangerous.
       It's more informed ... and  more confusing.
       It's more connected ... and  more segregated.
       It's more divided ... and more unified.
       It's global ... and more national. 
       It's more aware ... and more ignorant.
       It's faster ... just faster.
        And every year a new set of students to teach about now and the past,  about what their world is like because of events like this one 14 years  ago when evil attacked and so many people responded by making inspiring sacrifices for people they didn't even know. We should never forget because when we forget what has happened, we  can't make sense of what is happening.
       Teach on.
