What is a wife?

A wife is a woman who always responds enthusiastically, never restricts and never rejects your initiation for intimacy and sex. Any questions? Yes. The first question of course, what about that woman who 'sometimes' responds and sometimes doesn't? What if she is simply not in the mood 'sometimes'? Just demote her from your wife, to your live-in partner. As much as she has a right to say no to intimacy and sex, sometimes, she has to be okay with her husband having the right to not being in the mood to be legally married 'sometimes'.
