So you think this chap is doing the knowledge because he has a board on the front of his bike? We saw him at Rainham. Matt says that Rainham Taxis where we were going is probably a knowledge point. He tried to tell me what that means but I was too busy balancing my sketch book with the graphite drawings to dry in my airing cupboard as I have put too much fixative on. I sprayed them too close up and made them too wet. I'm rather upset, and shan't do that again. He later explained that when you're doing the knowledge you have to explain how to get from point to point taking the quickest and cheapest route.
