It is now two decades since I lived in Oxford. I was then a drunk and lonely puddle of a person, with only a gift for screaming; but no matter how low I sank, to paraphrase Alcoholics Anonymous literature, I never sank quite as low as to consider eating at the ’bab van (kebab van) outside Univ (University College) on the High (High Street); I preferred to dine in Hall (a hall).
