When I was younger, in most of the couples that I knew, the man was older than the woman. This somehow gave me the idea that men always grow up to be older than women. The younger son of my mom's friend was harassing me by saying that he was older than me. His mom said "No, Christopher, she is older." I matter-of-factly told her, "I'm older right now, but he's sort of right becuase boys always grow up to be older than girls." I was quite confused when she set me straight.
