That isn't why I am giving up. I am giving up because it seems that disagreement and pointing out flaws is now trolling. As you have no desire to have a proper discussion and would prefer insults, then I am bowing out.
You were trolling because you were purposely being obtuse in the definition of cohabitation, when you knew exactly what I meant. It was not an insult, it was a light-hearted observation on some of the obviously silly examples you gave, such as someone's boy/girlfriend staying over the night and dying....
