I asked that girl, ‘Would you teach them enough biotechnology to pass?’ And she said, ‘How would I do that? I don’t know the subject.’ I said, ‘No, use the method of the grandmother.’ She said, ‘What’s that?’ I said, ‘Well, what you’ve got to do is stand behind them and admire them all the time. Just say to them, ‘That’s cool. That’s fantastic. What is that? Can you do that again? Can you show me some more?’’ She did that for two months.”
