There once was a little line. The line was sad and lonely. “I want to be part of a shape,” the line said. “Then I would have friends and a purpose.” The line tried to join a triangle, but the triangle wouldn’t let the line join. “If you join us, they we won’t be a triangle any more, we’ll be a rectangle.”
The line tried to join a square. The square didn’t want the line to join either. “If we let you join us, we won’t be a square any more, we’ll be a pentagon.”
The line moved away from the other shapes and was all alone. The line began crying, and curled up in a small ball. Suddenly, the line heard a small voice.
“Look at that circle!” the voice shouted, “I want to be a circle like that.”
The line looked around but didn’t see any circles. “Who are you talking to,” the line asked the voice.
“You!” the voice said.
The line found a mirror, and looked at the mirror and realized that when curling up its ends had joined together, and now its was a circle. The line smiled and rolled away, happy that it now was part of a shape.
