I still say there are way to many people in this world to spend your whole life making just one miserable.
Which is why it's just as well that we live in a monogamous society and the shoe isn't on the other foot... cos having more than one spouse to make you miserable could make life feel like... er, Hell on Earth...
.... and try imagining for a moment, if you will, having to face/cope with more than one mother-in-law.

Now you know why lawmaker, in their greater wisdom, outlawed bigamy.... to save us from ourselves/multiple mother-in-laws.
