Everyone knows what it is like to be manipulated by moodiness. There used to be an antique dealer who was a master at this particular drama. He would look darkly if you said something vaguely silly and switch into strict school master tone, stentorian and morally superior. It was highly aggravating and also uncomfortable to be around. It was designed to make you uncomfortable and cause you to look for common ground with which to ease, or more accurately, appease the mood.
There is a lot of talk about false equivalencies in politics these days. The antiques trade is rife with false equivalencies where one piece is compared to another because they may look alike or serve the same function. I recently purchased a drum table and I have to say that it is one of the finest made pieces of English furniture I have ever owned. The table was made by a firm that truly understood how timber is best utilized. The table reeks of quality. Of course, it is brown and there lies the false equivalency. All brown wood is boring. How untrue that statement can be.
False equivalencies are essentially used to mask inequality. Moods are used to create an inequality, to put someone at a disadvantage. Their similarity, at least in my mind, lies in the essential dishonesty they engender. Of course, a bad mood is a bad mood and everyone makes false equivalencies, particularly parents with small children. But when the attempt is to be fundamentally dishonest, there is a knock on affect that forestalls intercourse and understanding. Not all brown furniture is equal after all.
