Kayla: Daddy, may I use your nail polish?
Me: Why don’t you use mommies?
Kayla: It doesn’t match.
Me: Uh, okay.
Now Kayla has one hand that is purple and one that is pink. The toes on her left foot are blaze orange and the toes on her right are cherry red. In my view, her toe colors exactly match the colors of polish and/or duct tape I use to mark my climbing gear. In her view, having blaze orange toes on the left foot and cherry red toes on the right is a perfect match.
