in this world, everything is seemingly the same except for "uncles". fat uncles are revered and respected. the story talks about a boy and his older brother and "growning up". it takes place at the childs 9th birthday, where 3 fat uncles are in attendence, sitting on lawn chairs with their big bellies and having a slightly yeasty smell about them. in this world, as a child matures, he or she is told to drink bitter milk to help him or her grow up. the 'growing up' takes place over the course of a few hours, where a child becomes an adult. this usually happens in high school, and as soon as the child grows up, he or she is allowed to quit school and begin looking for a job.
tony, the older brother, is on the brink of growing up. it happens one night and his younger brother comes in and asks tony what its like to grow up. tony cannot really describe it and says he doesnt really feel any different. then the kid asks where babies come from, and tony says, 'from a slit in a a fat uncles belly, but you know that." the kid says, yeah, i knew that-- i just wanted to ask you.
tony, after a few weeks, gets a job and moves out after a month. the kid goes on going to school, wondering when he will grow up. eventually, he meets a girl and they have sex. they talk and both agree they do NOT want to grow up, so they stop drinking their bitter milk. doctors come in and take their vitals each week as every child has this, and they find they are not close yet to growing up. both he and the gf pretend to be grownups and go to different towns, playing the part, or at least try to. they spot tony one day in a bar with his girlfriend, sitting at a table with a fat uncle. another time, they go to a farther town and meet a fat uncle there, too. they get a hotel room together, and the uncle excuses himself to freshen up. they hear him fart and take a dump, so they start giggling then run out and back home.
the kid one day is caught having sex with the gf, but his mother says nothing. later, the kid comes home one day from a night on the town with his gf, pretending to be grownups and awkwardly finds his mother, father, and a fat uncle in the bedroom. since his mother said nothing, he ignored the incident as well, although he was completely baffled.
on his 17th birthday, he has a party, which might be his last since hes getting old. he gets toys as kids do and some neighbors show up. his gf shows up too, and she grabs his hand and takes him up to the hill in town. they both wish to stay kids forever. he goes to make a move on her and notices her breasts are enlargening and her nipples have completely flattened out. she asks him not to touch her there since shes sore. she then goes to kiss him, but he is struck by a sharp pain. they both panic, and she helps lead him back to his house as his pain gets more excruciating. he gets home and passes out, waking up in the hospital.
theres a knock on the door, and its his gf. she explains to him that he has grown up. as he looks at her, he notices that shes cut her hair very short and has put on more weight...well, fat. she notices him looking, and she says that sometimes this happens to girls. he says yes.
the story wraps up with a nice tie-in to a moment they had shared-- a comment about peter pan and remaining a kid forever, but the reader is left wondering about a world where there are males, females, and fat uncle genders needed for procreation. i thought about this bizarre story for over a month
