I was six when it happened. I remember watching the whole thing on TV, and, despite the fact that I was too young to understand it completely, as the events unfolded, I realised that I was experiencing something immensely sad that would go on to change the world.
RIP to all the victims of 9/11.
My heart goes out to all the survivors, and the friends and family of the victims: it's always difficult to be the one left behind, when all you can feel is an all-consuming grief. Sometimes, the hardest thing to do is survive.
