There's no tragedy in life like the death of a child. Things never get back to the way they were.

I hope that tomorrow we can all, wherever we are, join in expressing our grief at Diana's loss, and gratitude for her all-too-short life. It is a chance to show to the whole world the British nation united in grief and respect.

We have lost an icon. Almost every night for more than three decades, Alex Trebek entertained and educated millions around the world, instilling in so many of us a love for trivia. My deepest condolences to his family, friends, and all who are mourning this tremendous loss.

In the months since the death of my beloved Philip, I have drawn great comfort from the warmth and affection of the many tributes to his life and work - from around the country, the Commonwealth, and the world. His sense of service, intellectual curiosity and capacity to squeeze fun out of any situation - were all irrepressible. That mischievous, enquiring twinkle was as bright at the end as when I first set eyes on him.

This soldier, I realized, must have had friends at home and in his regiment; yet he lay there deserted by all except his dog. I looked on, unmoved, at battles which decided the future of nations. Tearless, I had given orders which brought death to thousands. Yet here I was stirred, profoundly stirred, stirred to tears. And by what? By the grief of one dog.

I guess I just process death differently than some folks. Realizing you're not going to see that person again is always the most difficult part about it. But that feeling settles, and then you are glad you had that person in your life, and then the happiness and the sadness get all swirled up inside you.
