My oldest son (now 10) remembers the day, and the coverage, and some of how life was before, but his youngest brother was 3 months old at the time, and I think he was going through a lot of changes at that time (he also has a brother who was 20 months old on 9-11). Upheaval all around. They in turn know no different. I think about that often.
I will spend extra time today with each of them, but especially my 10 yr old, he's very attune to the news, current events etc, and he knows how we feel, so I'm sure he has the same anger/hurt we feel. I need to make sure he and his brothers have an outlet in case they need it.
I still plainly remember the first WTC attack...
The thing is that we, as adults know how the entire mindset of the world changed after 09/11. From very small to very large ways, there is so much of our world that has been modified to either acknowledge the fullness of the terrorism we are dealing with, or to fight it and prevent it, or to develope institutions, economies and cultures to see that it does not continue to grow.
Thus, security, education, jobs, politics, religious sentiment, world affairs and world problems have all been adjusted to a post 9/11 reality that we finally awoke to only on 9/11. The world was changing to this post 9/11 reality for many years, but we were not seeing those changes for what they were, until 9/11.
My fear is that the same sort of lack of awareness - of the real threat - is already happening with too many people, in regard to Iran.
