The events of yesterday have made me feel sick. I keep thinking about how it could happen, it seems like a terrible nightmare. I think about the people on the planes, knowing that they were going to die, how they must have felt when they realised what was happening. The people in the buildings, getting in to work, beating the traffic, hurrying so they wouldn't be late only to have everything disappear around them. All those lives lost, all the people left to grieve. It makes you realise that you can't afford to waste a moment.
