They’re (traveling teachers) useless sir. They teach us facts, not understanding. It’s like teaching people about forests by showing them a saw. I want a proper school, sir, to teach reading and writing, and most of all thinking, sir, so people can find what they’re good at, because someone doing what they really like is always an asset to any country, and too often people never find out until it’s too late.
