I'm not sure that we- that my parents did see a lot of him. He was a Professor in University College at the time, and I actually don't recall really meeting him or seeing much of him until- probably until I left school. But I do remember, as a Sixth Former, writing to him and saying, what shall I do to make a life in biology. And, he said- he wrote a very nice letter back saying, well for the time being you better get on with your school work. And that I did. But I was already beginning to look at his books- some of his books. And, of course, his children's stories were very much appreciated in the family, 'My Friend Mr Leaky' and others.
