Potts and The Doctor

Why does Bill Potts say that The Doctor is an "awesome tutor"?

Because he doesn't 'deliver' knowledge. He IS the knowledge. Being around him is a natural learning experience. Just having a simple conversation is a whole game-changing moment.

Whilst, of course, every teacher can't be a twin-hearted alien from Gallifrey, we SHOULD be living the knowledge and experience we have.

Really.
Truly.

Not trying to sell it, like it was pizza. Cardboard-boxed and delivered (Gods! I hate that word when teachers use it!) to the consumer.
