You know, you can see all the bands you like; you can meet all your heroes and shake hands with all your favourite film stars; you can eat in the best restaurants and drink all the top class wines. You can visit all the beautiful landscapes on earth. You can do whatever you like, but I know now that all I need to be truly happy is a nice long walk out with Lyn. I realised that this afternoon, as I trundled behind her through Greenwich Park. In that moment, as we steered our powerchairs under the ancient trees, the whir of our motors mingling with the birdsong, I felt truly content: if I wanted to be happy, that was all I really needed.
