One of my most cherished possessions is a letter written to me my sophomore year in college. My exams that winter finished early, so I was the first of my group of friends to go home. A few nights later my friends had a raucous end-of-exams party, involving much alcohol and a several illegal substances. Through the course of the evening they passed a notebook around, composing a letter to me. The entries begin coherently but deteriorate as the night wore on. By the end they were mere scribbles. You can imagine how much fun it was to receive the letter at home over winter break.
