Conversation {Tails}

This little conversation came after Alex asked me if it was cold outside.
Alex: Rosie must get cold. She doesn’t have a tail.
Me: That’s right.
Alex: Don’t most animals have tails?
Me: Yah
Alex: Are there any humans that have a tail?
Me: No, we don’t have a need for a tail like animals do.
Alex: That’s why we get cold easier than animals.
