This is a quotation from page 98 of the 1990 national bestseller entitled "You Just Don't Understand: Women and Men in Conversation," by Deborah Tannen, Ph.D. The implication is that revealing secrets destroys friendship, a hypothesis that is clearly supported by the anectodal evidence of the Tripp/Lewinsky case.
Evidently, friendship cannot endure the documentation and revelation of secrets ... anymore than can secrets themselves can survive public exposure.
Records are the enemy of secrets. Can it be that they are anathema to friendship as well? If so, what does that say about friendship? The answer depends upon the context. What may be acceptable, and fully expected in a social context, may be entirely inappropriate within the context of business -- commercial or governmental.
