BEST THING

I was thinking of all the good things that have happened in my life, and I find it hard to come to a decision as to what the very best thing to have ever happened to me is. The birth of my two children, my life in Africa, a helicopter flight over the Grand Canyon, and a lot of love from various people - far too difficult to select only one.

How does anyone manage to select only one thing, if so what has been the best thing that has ever happened to you?
