It was always amusing to me when my British drama teacher would use a word that Americans rarely use like "coach" or "metro" (as opposed to bus or subway). I had just big enough a vocabulary for it to be no effort for me to understand her, even if I never used such words personally, whereas everybody around me just went "huh?" I guess I'm finally noticing the times when I'm on the other side of that divide and have to really think about what the unfamiliar words mean in the given context.
