The speaker describes a body in the middle of decaying, and does it with a strange, almost tender calm. Worms live in the eyes, trees grow from the face, insects nest in the hair, and fungi sprout from the toes. Nothing here is treated as horror. The line "they make the sky more becoming" suggests the speaker finds a kind of beauty in the change, as if the worms improve the view.
The final line, "with all that, youre almost complete," turns decay into a process of finishing rather than loss. The body isn't ruined; it's being filled in by other living things. The casual tone, with its lowercase style, shortened "yr" and the joke about worms not yet eating "your dinner," keeps the mood intimate and darkly playful. It feels like someone speaking to a person they love, or to themselves, and finding comfort in the idea of becoming part of the living world.
