My longest standing friend came to visit at the weekend. Happily, relaxedly, we pranced around Edinburgh eating and drinking and having fine old times.

Until I decided proudly to tell her the ending of my script. I wonder if this moment will always stay in my mind. Walking along by the scraggy garage end of the Promenade in the evening (at 3:30) sun. And she says: "but they couldn't do that. It would be illegal."

DAMN YOU.

Of course she's right.
