I found living in a house with multiple females constantly bickering intolerable.
I cant for the life of me imagine seeking to add another wife to my household, the rivalry that would ensue would make your life a living H*LL. Mediating arguments between your wives would eat up enormous amounts of time.
Hmmmmmm...perhaps if you were able to present the draconian onus possibility of stoning, beheading under the guise of 'honor' killing...then perhaps all would be quiet on your western front.
It may quite things when I was home but the bickering would simply occur when I was not at home.
It is a simple fact that there can only be one Alpha female in the house. The other given is that there is always a battle going on as to who that is if there is more than one female in the house.
