I won't go so far as to say that a wife should have no friends, but there is such a thing as a wife being so wrapped up in her friends, letting them be her prime focus in life, having particularly overbearing or officious friends be her "handlers", and --- this must be said --- getting her dissatisfied with her marriage, possibly even going so far as to introducing her to men who they think would be better companions for her, than her husband is. And that doesn't even begin to touch the hazards of wives in the workplace, and the "work wife/work husband" dynamics that often emerge. Something about resisting beginnings? Or is that not a "thing" anymore?
Don't say it can't happen. Better no friends at all, than the wrong kind of "friends". I have seen many a marriage broken up by bad associations outside the home. And didn't we just get done bouncing back and forth the idea that a wife needs her husband's permission to go outside the home? I won't go so far as to say I advocate this, but there are some venturings outside the home that can be disastrous for both home and marriage --- and that goes both for the wife and the husband!
