"[My biology teacher] came into class and asked: 'What animal feeds on hydra?' We didn't know. He went right around the whole class asking. Everybody was guessing, and then, finally, we said, 'Sir, Sir, what animal does?' And he waited and waited, and then he said, 'I don't know. And I don't think Mr Coulson does either.' He burst into the next room, got Mr Coulson and dragged him out by the arm, and he didn't know either! It was a wonderful lesson, I never forgot it and neither did anyone else: it's OK to not know the answer."
