I've heard about situation like this before. "Wife beating her husband mother"
The husband didn't show much reaction and begged his mother. He left for his in-law house and drag his wife's mother and beat her up like his mother was beaten.....
When it comes to Complaining, Murmuring and Nagging, I can guarantee you to leave it for Africans..
Has the Complaining, Murmuring and Nagging changed anything since 1960...π
