Well, not quite, though it is a case of “when I was your age”. I was reading the text for the reference course that I’m taking and came across a sentence that mentioned the “eight planets of our solar system” and I realized that this is one of those facts that have changed for students in school today. I remember when our solar system had 9 planets. I also remember reading about the USSR until I was in second grade. Seems so insignificant, but it shows how “facts” are always changing.
