Simon, I could tell. I’m good with cows. Also with calves. I once asked a crowd of noisy swallows to quiet down, as I had a headache, and the swallows did. I have sometimes wondered: Why didn’t God leave the world as frank and easy to understand as a cow? Instead, it’s all a puzzle, for us to tease out which points of light are planets and which are stars, and who can be trusted and who cannot.
