It was from the beginning a decision to tell this story from the eyes of a ten years old me, and do not relate how I see it now with knowledge not even from what I learned a year later.
Another big decision was to add to it a part about "now" and link it with "holding hands" with the past: that leaves all with a warm feeling and also a non told but important second message.
Toastmasters to whom I told this story in my different clubs (it was each time from a project Manual speech), and asked advice, all gave me very useful advices.
Where should I stretch to hold the suspense longer, where should I change my face and make more pause, for example. Joanna Yates, producer of Spark London, helped me a lot to shorten and cut from my long initial beginning where I talked, for this story at least, a lot more of my cousin.
Telling it some other time, perhaps I could add back as different blocks can be taken out usually and added depending of the circumstances. But this story I told so many times that I learned it as is, and last year as I went to give a keynote in AYR, West of Scotland, I met two young women on the train and told them the story. It went so easy and they were fascinated.
