The flatliners lived in a multidimensional world similar to the humans. However, they only perceive two dimensions and so everything is flat.
Both beings, being very inquisitive met each other. The flatliner explained the problem he was having when he went to fetch the water. The human could see the problem, because, unknown to the flatliner, there was a hill between his house and the well. So he directed the flatliner to go around the hill. The flatliner was very pleased as he was now able to collect his water with ease.
The human was very pleased to have helped and went back to his stressful draining world.
