The abnormal mind is quick to detect and attach itself to this quality when it appears in a normal person, and so it came about that in college I was unjustly accused of being a politician, because I was privy to the secret griefs of wild, unknown men. Most of the confidences were unsought-frequently I have feigned sleep, preoccupation, or a hostile levity when I realized by some unmistakable sign that an intimate revelation was quivering on the horizon-for the intimate revelations of young men or at least the terms in which they express them are usually plagiaristic and marred by obvious suppressions. Reserving judgments is a matter of infinite hope.");
