O: There are 4 people in a circle house: A mother, a father, a maid, and a baby. One day the baby goes missing. During the interrogation, the mom said she was cooking, the dad said he was on the way to work, and the maid said she was dusting the corners. Who kidnapped the baby?

A: The Dad?

O: Nope.

A: Ah, I get it! The wife was probably lying, so the mom?

O: No. It was the maid because a circle house doesn’t have any corners, girl.

This is a bit of a puzzle but the answer is laid in plain sight. The setup of the riddle gives you the answer. It’s only a matter of listening carefully and knowing your math. Anyone unfamiliar with geometry would be quickly pointed out. The informant communicated that all the riddles she knows now were ones she learned in elementary school which is why it’s so important for them to keep telling it. Riddles can be regional. O’s experience with these in elementary school allows them to tell who experienced a similar community during their formative years.
