You are right that I don't know what happened or what kind of a letter you wrote. I know that to "cast pearls before swine" is a Biblical reference. It is usually used by someone who is in the business of trying to change other people, and finding their efforts are not appreciated.

One of the criticisms against the communication style that men tend to prefer is that it has a focus on identifying a problem and solving it. Some women tend to do the same thing. I have read that often women prefer to discuss how the problem made them feel, with the focus on being told that their listeners understand how they feel. In general I tend to be one of those people who jump to diagnosing a problem and looking for solutions with only the most cursory attention to the feelings involved - which are at most only symptoms of the main issue.
