Why do parents hate it when their children prove they are wrong (when they are actually and logically wrong)?
This is one problem I have with many adults today. Here is the answer. Because they think they know everything. They assume that just because you are a child and they are the adult. That they have the right to talk to you however they want and not expect a child to stand up to them. If you are dealing with something like this tell the parent “I am a human being, I know something, and I have the right to tell you that I do.”
