The most prominent example of a time that someone with more power or privilege than myself tried to explain something to me occurred about three or four years ago. I don't remember how the conversation started, but it ended with my father trying to explain to me how the female reproductive system works. Mind you, three/four years ago, I was 17 and had quite a bit of knowledge about the female reproductive system. One of the moments that sticks in my mind most strongly was when my father started to make a point by saying "girls have two holes down there..." (for the record, there are three) I told him that he was incorrect, which started him on a tirade about how there are two, despite both my mother and I trying to tell him that he was mistaken.
This was memorable to me because he was telling me that my mother and I were wrong about OUR OWN BODY PARTS.  I was amazed that when two people that clearly have more experience in this topic than himself told him that he was mistaken, he did not accept it. I would have expected him to take that as a sign that he didn't have a firm understanding of the concept. He did not take this as an opportunity to learn more, he argued that we were wrong. He was so sure of his ideas, that he tried to tell us that we were the ones that didn't understand what was happening in our own bodies. Like Rebecca Solnit's example with her book, my father was trying to explain to me what anyone may expect me to know a bit more about than him.
