Oh my God I was trying to teach my six year old sister how to sing Row Row Row Your Boat as a round (you know, like she jumps in one line after me), and she kept jumping in to sing the same line I was singing (“gently down the stream” instead of starting in with her own “row row row your boat”), so finally to show her what I meant, I recorded myself singing and then played it back and jumped in after myself. And when I finished I looked at her expecting her to be like “ohhhhh!” but instead she just looked at me and was all like, “uh, you did it wrong.”
