Two skunks in the forest

Have you heard the story of the two skunks named In and Out? They lived in the forest with their mother skunk.

And whenever In was in, Out was out. And whenever In was out,

Out was in. One day, when In was out and Out was in, mother skunk said to Out, “Out, I need you to go out and bring In in.”

So Out went out and immediately brought In in.

And their mother asked, “My, that was fast

! Out, how did you find In so quickly?” And Out said, “It was easy. Instinct.”
