My father is a college graduate and a retired airline DC-10 captain. He made a living and kept hundreds of thousands of people safe by always being right.
While my parents and I periodically gather around the kitchen table and my mother begins reminiscing about past holidays and special memories, she will sometimes preface her story my mentioning the year, month or season that the event took place. If it's not according to how my father remembers it, he'll interrupt and correct her. Sometimes in a slightly condescending manner because she's gotten the story wrong.
Is he technically correct? Possibly, and perhaps even likely, but is he right? Does interrupting a story where that kind of detail makes no difference to the point at hand, and hurting my mother's feelings, make him right? No, of course not! He may be correct technically, but wrong in a moral way of dealing with someone he's supposed to care about.
Does a potato absorb salt from a pot of salty soup? Is it a real fix or a placebo? Or does it even matter?
