Who could ever forget that day? The day the world was changed forever. I remember arriving at school. It was clear that something terrible had happened, something I wasn't privy to.

You see, we had a rule in our house and that was, no TV in the mornings, no TV, no news.

But now I knew and in that moment I realized that the world was becoming a threatening place and the fact that this generation of children would be the first to watch war taking place on television, sent a shiver up my spine.

In class, my young students just wanted to re-enact the scenes, the carnage. To seven-year-olds it's all pretty cool, and so I allowed them to...on whiteboards, chalk boards, wherever they wanted to illustrate. I had no energy for teaching. Anything I had planned seemed totally irrelevant.

All I wanted to do was go home and be with my family.

Yes the world was, and is, forever different.

A very thoughtful, truly inspirational post, Tim.
