Told in the past tense, "Together" is a speaker's look back at a happy time with someone they loved. Each stanza begins with the same words, "Together we were," and gives the couple a new pair of identities: rockets and roller coasters, jesters and jokers, dancers and dreamers. The pattern feels like someone counting treasures one by one.
The images begin huge and wild. The couple spirals into space, where Earth looks "so small, so insignificant" next to them, which captures how a new love can make everything else fade. Then the poem settles into something gentler: laughing, drinking too much, waking up content, and finally dreaming under an old oak tree while the stars seem to promise "forever and always."
The mood is warm, playful, and a little wistful. The past tense and the plain closing lines suggest the speaker may be remembering this happiness rather than living it, though the poem never says so outright.
