应该是这个意思

 

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.

应该是下面这个意思：

其实，那些推心置腹大多是自作多情--每次我看出苗头，有人要向我倾述衷肠，我就常常装睡，或者装作有事，甚至用轻佻来激怒他们让他们不要开口，那些年轻人的表白，至少他们的言辞，常常是陈腔滥调，欲说还休，言不由衷。
