London diary - genesis

10 AM on a friday morning, walking towards Hampstead Heath, north of London. Talking with Mila about characters of Lost and the benefits of watercress to prevent cancer (besides complaining about life).
We are cut by a motorcyclist who stopped and started shouting inside the helmet, very, very angry. Don't have a clue in which language. Not even if it was oriental, slav or what. We went on our way, resuming the talking. We thought "hey, why don't we start a diary?"
