I have a hard enough time trying to figure out the female thought process of one wife. And I’m sure every female thought process is different than the next…..having to try to figure out two people at the same time? My brain would explode. (Not to mention that each wife would probably be CONSTANTLY comparing what you do to the other. Oh but you did this and that for her 30 times and only 29 times for me, don’t you love me as much as you love her!??!?!?
Back then it was probably easier to deal with multiple wives because you had more of the day to yourself but today…you work well into the evenings, back then soon as it was sundown everyone ran to get home because of robbers/killers/animals/etc.
Besides….I doubt you would find more than a tiny handful of women who would be willing to even do this.
