adulting

As a child he wanted more than anything to 'adult'. To 'adult' was a verb that meant to to be recruited into this wonderful elite circle called "the adults", who always knew and controlled everything around them,

drove cars, drank alcohol, smoked cigarettes, ate as much ice cream as they wanted, played video games after sleeping time

The "adults" were all-powerful, and sometimes all-knowing gods who had the final say in everything. Even when another adult did something bad, it was the act commited by a god that had this aura of default immutability around them(that was challenged whenever it went against his wishes).

He was disillusioned and heartbroken when at least he realized that he was now an "adult" instead of the "child" that he still was when(he had to do some administrative procedure that is made him realize he was an adult)

He realized that the god known as "the adult" was more nothing more than a "child" who simply grew, and changed his appearance and mind. He became the god of his own domain composed of cars, store-bought ice-cream, video games, and his own fucking mess.
