Tomas experiences change as a series of small betrayals. His voice, which used to be reliably his, stutters and drops, refusing to obey; laughter sometimes breaks into a higher, foreign note. One morning he finds a soft, wet stain on his pyjamas and freezes as if the world had narrowed to that single mark. He is embarrassed and fascinated in equal parts, flipping through a textbook he never noticed before. His father, awkward and tender, gives him deodorant and a half-explanatory talk about “growing up,” which lands like a thrown sheet — protective but not entirely covering the questions underneath.
