Catherine's poem begins as a list of opposites: liking and loving, singing and crying, smiling and being afraid. Together they sketch what it feels like to be a person, with ups and downs that never settle. Some lines hint at escape, such as wishing you could fly away or finding happiness only in dreams, so the speaker seems to be carrying some pain.
Midway through, the poem turns to how people change. Small events can make you shrink back, and those events reshape you into someone different. Then the speaker lists pronouns (they, them, he, she, you) as if the blame could land on anyone. The final lines get more direct. The speaker says the moments that changed them were caused by "you," and warns that hating the speaker now amounts to hating yourself.
The mood is raw and defensive, a mix of hurt and challenge. The unpolished spelling and the abrupt line breaks add to the sense of a feeling written down quickly and honestly.
