My girl can fold her tongue. I can not. Everyone in my family but me can do this. Matt, Max, Lew and Della...but not me. My mom can fold her tongue. I've heard that this is a genetic issue. So I am guessing that my father can NOT fold his tongue. Is it true, Dad? Are you responsible for my being deficient in this area? Let's get to the bottom of this so we can move forward.
