Here, a person steps into the shower and ends up face to face with their own mind. With nothing to distract them, the speaker is left alone with their thoughts, and the happiness they long for feels "far yonder," out of reach and somewhere in the distance.
The warm water seems to blur everything. It makes the mind "foggy," yet the thoughts the speaker wants to leave behind refuse to wash away. They stay, and they weigh the speaker down. The sadness builds until the final stanza, where a sharp realization lands: the happiness they have been chasing is "bad." The poem doesn't spell out why, so we are left to guess. Perhaps the speaker senses that what they crave is unhealthy, or that it can't truly satisfy them.
The mood is quiet, private, and heavy. The short, plain lines and the abrupt ending make the speaker's confusion and discouragement feel raw and unpolished, as if we are overhearing a thought that was never meant to be said aloud.
