For a left - right story, consider this. A man is driving and reaches a split in the road. To the left is a narrow, winding road leading to a small, quiet town. To the right is a wide highway going towards a big city. He chooses left. In the town, he meets friendly locals and discovers a local fair with amazing handicrafts and delicious food. It's a simple but charming experience.
A left - right story could be about a cat. The cat is at a garden entrance with two paths. The left path has a lot of bushes where it can hide and hunt mice. The right path has a sunny patch where it can take a nap. The cat decides to go left. As it sneaks through the bushes, it spots a big, fat mouse. It chases the mouse and after an exciting chase, catches it. This little adventure makes the cat's day.
