He realized it very soon, he was 2 or 3 years old. He could save the world!
Nobody knew about his ability, he tried to tell Mom once, but she said “Don’t be silly” so he gave up.
He kept on his rescue work though: every day he closed his eyes and saw what he was supposed to do, one time there was an ant in trouble, another time he should throw that very stone into the river at that very moment, one day he had to hold his breath 38 seconds, another day he was asked to launch an encoded message using a mirror and the sun. It worked perfectly for years, but one night he had a strange dream and he woke up embarrassed and wet...
From that night on, when he closed his eyes he didn’t receive the guidelines to world salvation anymore, he just could see those delicate and soft and full of beauty and perfectly round and puffy thingies that girls use to keep their heart warm.
