I don't know what to call this.

Part of growing up and maturing is learning that your parents and other elders aren't as perfect as they seemed before. I heard or read that years ago, and I think that there probably is little dispute about the truth in it. I recall very well when I realized that my father wasn't an infallible memory bank with a recording of anything done or said in his presence. Of course, he's only human, and no one remembers everything. For other people, such a realization about their parents comes regarding a more severe and serious failing.
