An artist has a 6 year old child who also likes to draw.
His child drew a horse.
The artist told him, "You drew the horse wrong."
The child replied, "How did I draw it wrong?"
The artist said, "Why does the horse have wings?"
The child replied, "Why can't it have wings?"
The artist said, "It isn't a horse if it has wings."
The child replied, "Then why did you call it a horse?"
