Steve Mc, What I mean is that they are in for a rude awakening when she finds that he can fart and burp just like a human, and he finds that she doesn't do much housework and he has to pull more than his share of the load- for example. They may think of this now, and feel that their love will get them through anything...or whatever they are thinking. The reality of it will be very different.
God forbid that he has a real flaw, like being cruel to my children, running around with other women, etc.
