My business here is to teach you and I shall do my best to make my teaching as interesting as possible. If at any time I say anything which you do not understand or with which you do not agree, I would be pleased if you would let me know. Most of you will be leaving school within six months or so; that means that in a short while you will be embarked on the very adult business of earning a living. Bearing that in mind, I have decided that from now on you will be treated not as children but as young men and women, by me and by each other . When we move out of the state of childhood, certain higher standards of conduct are expected of us.
