For those of us with teens, it is a confusing memorial to things they were too young to understand at the time, but probably something they want to understand better now. I spoke with my own teens about what happened to us as a family that day, what happened at their schools and how we struggled to explain to them what was happening and why they should be not afraid. They had vague memories of the day and they wanted to tell me of their memories and their misconceptions. I was very surprised at what they remembered of the day itself.
I recommend talking to them again and remind them of what we were so wrapped up in at the time and why things changed. This is possibly their first chance of living history which their children will learn about in school and what they experience this weekend will be something they can share with their children and grandchildren.
