A married man may not and will not have any close dealings with the wife of a man younger than himself. It is not considered fitting that he should speak to her. If he wished to have any communication with her, he would do so through some third person. It would be regarded as a wrong thing to do if he were ever to touch her. The only explanation that the natives give of this custom is by saying that a man feels "shy" or "ashamed" towards his younger brother’s or friend’s wife. The custom is exactly the same with respect to the wife of any younger man, whether a brother, a cousin, or a stranger.

This custom depends on the distinction between older and younger. A man may be on terms of familiarity with the wife of a man older than himself, whom he would treat much as he would an elder sister.¹
