Two people, hand in hand, stare at the moon and feel completely at peace. The speaker describes a love so settled that nobody longs for the other anymore, because they are already together. Even the images of height, standing "up in the clouds," suggest a happiness that lifts them out of ordinary life.
The most interesting line is the one about weapons, now "stashed, / In the corners of my mind." The speaker doesn't say they are gone, only put away. That hints at a guarded past, perhaps a habit of defending themselves, which love has quieted. The poem then turns to a simple question: "Are we in love? / Is this joy?" The one-word answer, "Yes," stands alone, and the final line states the result plainly. The mood is calm, tender and a little dreamlike. The short, direct language makes the happiness feel sincere, though the speaker seems to be reassuring themselves a bit as well.
