Do you ever get the strange feeling you’re being watched? You are

Tom and I borrowed our friend’s Mini to drive to Canary Wharf. We had been lent it to collect for him a consignment of lighting fittings ordered from John Lewis, which he had no time to collect. This was kind of us.

Motivated thus by charity we drove off towards the smart new shopping centre within the Docklands development on the Isle of Dogs in east London. We must have looked an odd pair. Tom, who (it is fair to say) does not over-dress, is twenty-something and resembles a younger Hugh Grant dragged through a hedge. My habit is to throw on whatever assortment of clothes lie on my bedroom floor. I had not shaved for a few days, and had mislaid my hair comb. Still, the security man let us past the barrier where they stop you and ask your business in Docklands. Tom said ‘John Lewis’ (one does hope al-Qa’eda never tumble to this password) and the barrier lifted.
