Perhaps in reflection of the genetic fact that a released ovum dies within a day if not connected to an available sperm, ovum bearers also seem blindly driven to establish and maintain social connections in the people world; meanwhile sperm bearers seem to be equally driven toward independence, even as the sperm we bear are death-destined if they do not arrive and be singly selected for potential immortality.

And perhaps in reflection of these biological facts, women are commonly moved to prepare for, seek, and enjoy company of others, while living with men who may be happier with just us independently together.

Whatever the basis for these apparent gender differences, when the two contradictory modes are brought together in marriage, with two spouses living in one house, conflicts inevitable arise when one spouse or the other tries to practice their own mode–for instance, when a wife delights in preparing for and having company or a husband resists "entertaining others" and tries to keep just us together alone.

A predictable challenge is inherent with spouses who do indeed care for one another, but at the same time want to enjoy their own natural mode of personal living–she to make and keep connections with others, and he to carefully maintain his independence, both with her as well as any company with others.

Obviously, some type of pragmatic comprise is essential for living well together.
