Overheard at our house...
Blond Twin: "Did you get this at Best Buy?"
Mom: "Did we get what at Best Buy?"
Blond Twin: "The honey."
Mom: "Why would we buy honey at Best Buy?"
Blond Twin: "On the back it says best by."
Mom (laughing): "No baby, that means it tastes best before that date. It's not buy like you purchase something. It's by like a due date."
Blond Twin: "Ohh, that makes sense. I thought it was funny that you'd buy honey at Best Buy."
