I know that the wife must be obedient to her husband and it makes sense. Since family is like an organization there must be someone in charge. I do not see any oppression or problem in this.
But what if the husband is in the wrong? Or the husband is telling the wife to do something that is sinful? Or let's say some relative of the wife is sick and she wants to go see that relative but her husband refuses to give her permission. Can she speak up in an acceptable manner? Is there any other case where the wife can protest or disobey her husband?
Another thing, can the wife tell her husband not to mix with certain persons she doesn't like?
