Ronnie's poem uses the sky as a way to talk about a breakup. The speaker looks up and is reminded of an ex-lover, and the image shifts as the poem goes on. The bright daytime sky becomes a cover for the night, and the speaker realizes she was the one "way up high / In the clouds," so caught up in the relationship that she missed what was really happening.
At night, the mood turns sadder. Each star feels like one of the lies the ex told when they were twenty-one. The speaker used to find the sky pretty, but now it only stirs up hurt and distrust. The closing lines are the sharpest: he promised to stay "just like the sun" but left "just like the moon." The poem is simple and direct, with short rhyming couplets that sound almost like a diary entry. The overall feeling is quiet heartbreak, mixed with a bitter kind of clarity about being deceived.
