Now with your last para I can agree. We DO have to get on with our lives, be grateful we have them and live. Any other maundering means that the terrorists win.
I can say that when I saw the news in London come, I felt a moment of pride for you bloody English, that people returned to the subway and seemed to automatically regenerate the Blitz mentality. It's the only way to go. I wish they would take out the stupid 'security' at airports and allow passengers to accept that perhaps flying is a risk for no matter what is done (viz CCTV cameras) terrorists cannot be stopped. All of life is a chance, some chances are worse than others.
