Yesterday morning I settled down peacefully on a bench to sketch this tour boat. Five minutes later, a bus roared up and 456,988,345 tourists poured out. I hurried away without finishing my picture, but it was a lousy sketch anyway, so it was no big loss. Tonight I came across it again, messed around with it for a minute, and wandered off to make some tea. When I got back to my chair, I was surprised. "Hey, I sort of like this. Why don't I just leave it like that?" So I did.
