I learned a great deal at university, about half of it from a man called Raymond Foulk. Ray was not Professor Foulk or even Dr Foulk: Ray was a near contemporary — he was in the year below me — but a mature student, then aged about 44. Shortly before he arrived at the beginning of my second year to read architecture, the college investigated his past life and sought to exile him to first-year accommodation far outside the college walls to prevent him corrupting the youth.
