Sheldon Vanauken was a student of the English professor and Christian apologist C. S. Lewis in the early 1950s. He recounts in his book A Severe Mercy the story of his last meeting with his mentor when Vanauken was leaving Oxford for the United States. Over one final lunch together at a pub, they had spent time wondering aloud about the nature of life after death. When they had finished eating, they stood outside of the pub, talked for a few more minutes, and just before parting ways, Lewis said to Vanauken, "I shan't say goodbye. We'll meet again." The great apologist then plunged into the traffic to cross the street while Vanuaken watched his friend walk away. When Lewis got to the other side of the street, he turned around, anticipating that his friend would still be standing there. With a grin on his face, Lewis shouted over the great roar of cars, "Besides—Christians never say goodbye."
