In an enclosed forest, nearby a small, quiet village, was a river that stretched for as far as the eye could see and was as wide as any house that was built by the villagers. The flow of the river was intense: strong enough to break any wood that was unfortunate enough to be caught in its current. The water reflected the moon that shadowed the landscape. At the edge of the large river was a bridge that allowed travelers to cross with no risk, for jagged rocks were scattered throughout its surface area.
From the narrow opening of the forest, three kids emerged. The eldest boy was thirteen years of age, the second only eleven, and the youngest who until recently turned nine years old. It appeared as though they were enjoying a midnight leisurely walk. As they crossed the bridge, the youngest spotted a brown sack that was caught in the middle of the river, which exposed gold and silver contents. As he gazed at it, a greedy expression formed on his face. Immediately, the boy headed down the bridge and made his way towards the edge of the river.
The other two, who had spotted the treasure at the same time, pondered for a moment. The second oldest repressed his immediate desire and began to scheme a way to obtain the treasure while avoiding the painful risks. After intensely focusing on finding a safe method, an idea erupted in his head – maybe I can safely reach the treasure by using a large branch from a nearby tree. It was almost a revelation of sorts. A minute later, the boy retreated to the forest to find a branch long enough to reach the sack.
The eldest, who was far more educated than the other two, weighed the probable results. The treasure may have the worth to cover my basic needs, thought the eldest boy. However, he refuted, the river is far too dangerous and therefore I might withstand major injuries in attempt to salvage the treasure. With such a dilemma, he decided that the effort was meaningless regarding the consequences. In light of his own morals, he had little tolerance for greed. He felt as if the immoral action in such a scenario were to ambitiously retrieve the treasure. He rested on the wooden railing, satisfied by his own contemplation.
The youngest was in the middle of the river now. It seemed to be that he jumped from rock to rock to get in reaching distance of the treasure. Carefully, he stretched his arms towards his wealthy future. In mid-action, his foot had begun to move slightly. A few seconds after his realization, the youngest found himself engulfed in the river’s abyss. He flung his arms and legs at a desperate attempt to catch himself on a nearby rock. The eldest ran off the bridge and hurried to his friend’s rescue. However, before he could arrive at the river’s edge, the boy had disappeared among the cluttered rocks.
His body paralyzed, the eldest boy’s eyes searched the river’s surface. For the next few minutes, nothing appeared from the river’s volume, including the treasure that invoked the youngest child’s gratification. The second oldest emerged from the forest. After scanning the dimmed area, he looked at the eldest, his eyes begging for an explanation for the youngest child’s absence. The eldest attempted to speak but couldn’t find the words. He looked down at his hands, which rapidly shook in response to his overwhelming grief - as fast as the river’s current that took away his friend that day.

Id  - The youngest child who operated on the pleasure principle, who demanded immediate gratification.
Ego – The eleven year old who operated on the reality principle, who attempted to satisfy the id's desires in ways that will realistically bring pleasure rather than pain.
Superego – the eldest child who debated a moral choice and used standards as judgement.
