Had a minute of silence at work for 9/11 today. Talked to a coworker who was in first grade when the attacks happened.
Hard to explain the different world that existed before then. Travel, Finance, Military Service, things changed tremendously.
The attacks happened in 2001, I went to the recruiters got on a wait list*, got some things in order, and was off to training by 2002. Those attacks would broadly define the next decade of my life.
*- Not joking, there was a months long waiting list to ship off to Basic Training with all the post 9-11 enlistments. Hard to imagine today.
