I’ll start by telling you a story. I’m telling it to you so you know what happened. I’m also telling it to you because it helps me to tell it. And because it helps me, I am saying that if anything like this has happened to you, it may well help you to do the same: to tell your story. You can do this in any way you like. The important thing is to tell it.

The story begins at Paddington Station in 1999. From there, I ring home to see if my son Eddie is in. He’s nearly 19. Sometimes he’s there and sometimes he stays with his girlfriend. If he’s not there, I might go and visit someone else. If he is there, I’ll go home and we can have a chat.
