In an experiment about survival, the tank was being filled with water and in it were, the monkey and it's infant. As the water level was rising the kid hugged mother tightly. Scientist ticked one of the boxes that said something about trust.

As the water rose, mother put the baby on his head. Another box regarding love got ticked.

As a last stage of the experiment, water kept rising and mother soon went out of the breath. In a desperation, she put the kid underwater, climbed on her and took a deep breath of life. A smirk on his face, scientist ticked final box, something regarding survival.

Before water stopped being poured, to his disbelief, mother pulled up the baby putting it back on her head for it to breath. Smile on his face faded. He turned off the nob and he looked at the end of the form in his hand. For him to tick, there, left for him, was nothing.
