When your best friend's mother's lazy-ass-two-timing-no-good-rat-bastard-cheating-manipulating-rotten-verbally-abusive-did-I-forget-to-tell-you-for-the-first-YEAR-that-we-were-dating-that-I-have-a-wife-oops-maybe-I-should-have-brought-that-up-in-one-of-our-conversations boyfriend promises that he really is going to leave his wife but he wants to wait until January first, I would not recommend saying either of the following:
1. Has your mother developed a crank habit of which we have been unaware, and
2. What does he want? To use her one more year to get a break on the taxes?
Even the longsuffering may falter in a moment such as this.
