Feet

We're sitting in the waiting room waiting for my car to be inspected when I realize Lorelei was wearing her shoes on the wrong feet.

 I told her and she said "Oh..so this one goes on my LEFT foot." I looked and sure enough she was correct. "When did you learn left and right Lorelei? What is this foot?" (pointing to her right foot).... "My OTHER left foot" she replied proudly.
