I think there's one other thing that's worth thinking about, and that is that many of our students come into the University for one-day schools, for lectures, for activities of this kind, and this gives an opportunity for a kind of reciprocal traffic, if you like, so that people outside who often have very odd ideas of what universities do and what they're about and what they're like, can actually see your University, participate in its activities, and we can see ordinary folk who sometimes ask the shrewdest questions and make sometimes what seem to be the most penetrating kinds of points about the sort of things that we take for granted.
