Skunks Called In And Out

Once upon a time there were two little skunks named

"In"

and

"Out."

They lived in a hollow tree with their mother. Sometime In and Out played outside, but other times they played inside. One day In was out and Out was in. Mother skunk told Out to go out and bring In in. So Out went out and in a few minutes he came in with In.

"My my, Out," she said, "How did you find In so quickly?"

Out just smiled and said, "Instinct."
