SB, As far as my understanding of MLC goes, when a person is going through it there is a personality change. They become the opposite of who they've been, hence the term, alien.
I know people who have never taken responsibility for their actions. It's easier to blame someone or something else than to admit you were wrong, made a mistake, used bad judgment, etc. Most of these folks think they're entitled to things without ever putting in the hard work. They usually lack ambition and drive and wallow in self pity, especially if they don't get their own way or something doesn't go quite like they wanted it to.
Living with someone like that would certainly get very tiring.
