At 87 years young and sharp as a tack, my Mother-in-Law is without question, a force to be reckoned with. Opinions ohne Ende (without an end)  and an array of off-color commentary to match, she is (hard stop) one of the most opinionated (albeit at times brutally so) people I know.  Ours is solid relationship, one that comes with an understanding and a level of warmth that five years in still leaves me laughing in disbelief one minute and gritting my teeth the next.
