First, the majority of men and women don't enjoy talking with each other on a transparent, vulnerable level. In fact, in most social gatherings you'll observe men and women in separate groups. I don't agree. I believe it is one of the consequences of the sin that originated in the Garden of Eden. Men have developed their set of rules and initiation rites that exclude women.
Women do the same.
These deeply rooted patterns get passed on to new generations, with the perennial results of alienated relationships. It's easy to see it in the other sex, but too often we are reluctant to admit that we are as much a part of the problem as they are. In our generation a sophisticated belief developed that men and women are irreparably different, and the best way to exist is to admit the difference and learn to live with it. We smile, nod our heads in agreement as though we've solved the problem, and go on with our gender-soaked conversation. By stressing how different we are, we've invented a convenient excuse to avoid facing what sin has done to us.
