When you get to my age life seems little more than one long march to and from the lavatory.
One's mind has a way of making itself up in the background, and it suddenly becomes clear what one means to do.
Very often a change of self is needed more than a change of scene.
I am sure it is one's duty as a teacher to try to show boys that no opinions, no tastes, no emotions are worth much unless they are one's own. I suffered acutely as a boy from the lack of being shown this.
