Phepilethuli's poem is about feeling unseen while everyone assumes you're fine. The opening lines set up a run of contradictions: the speaker has a voice but stays silent, has eyes but is blind, cries but no one notices, screams but isn't heard. Each line shows an ability that has been made useless by being ignored.
The repeated couplet about the "happy" girl is the saddest part. The world decides she is happy, so she plays along with "a distant laughter," a laugh that is performed rather than felt. Even with friends and family, she feels she doesn't belong, and she blames herself, calling herself too "dumb" and too "ugly" to matter to anyone. The question "Where do I fit" is left hanging.
The ending is bleak. Time keeps ticking while she fades "into the unknown," imagining that whoever finds her bones will think she never existed. The mood is lonely, hopeless, and quietly desperate.
