Riddle: I live in a circle surrounded by hair sometimes I go out and sometimes I stay in. What am I?
Answer: A Belly Button
It might sound confusing at first to think about how a “belly button” can go out or stay in as if it detaches from your body and travels as it wishes. But of course not. The “going out” and “staying in” phrases in this riddle actually mean you being dressed or naked or possibly wearing a crop top. And also although some people don’t have any hair around their belly button, most of us do! And I assume that each person’s belly button is circle-shaped. So a belly button is a circle “creature” that lives inside a circular hair border… And it can go out sometimes!
