True stories....when my son was 9, driving him home from school, out of the blue he says "what's a vulva?" Instinctively I said "it's a car"
Poor kid probably went back to school the next day & told his friend "I know what a vulva is, it's a car" We still razz him about that now that he's in his 40's, good laughs

Then when my dad was elderly he use to call his urology doc a "eulogy" doc, uh no dad I hope not & he had COPD & called it "coped" Tried to correct him couple of times but he kept calling it that
