One of the most gratifying things in life recently has been the fact that a few brethren wrote that they missed these occasional notes from an ivory tower. Even Theophilus unbent enough to write: "I really miss your yellow sheets. I used to read myself to sleep with them — but now I have to take sleeping pills. It would be cheaper for me to take a collection for Valpo than to buy all those pills." In answer, therefore, to this tidal wave of demand I have gathered my notes for this invasion of your privacy during Advent."
