A male approaches the door of a female and finds that she has filled her apartment with the plastic balls used in children’s ball pits. He is surprised and confused so he inquires about the reason for her actions. To this she replies that they are adults now and the decisions they make, along with the consequences of those decisions, are entirely up to them.
The actions of the comic’s female character represent those of a young adult whose fear over the sudden realization that they are adults with responsibility cause them to act out in a childish manner. This fear of adulthood is often caused by someone not fully experiencing their youth, due to a variety of reasons including: social awkwardness, overbearing parents, advanced childhood talent or fear.
It is this condition that leads to adults taking interest in model trains, sports cars, dinosaurs, alcoholism, ball pits, younger sexual partners, yelling and more.
