Part two of the diptych, which starts with Morning Song its pair. As in Morning Song, 3 verses of 5 lines, with each verse having an A-B-A-B pattern. The 5th line of each verse rhymes. Unlike Morning Song, the rhythm is less steady. It wavers between iambic (short-long), and trochaic (long-short), its mirror. But some of the lines end in what would musically be called a triplet - 3 notes of equal length. Or some times its just two equal notes. You can force "pretending" into short-long-short "Pre-ten-ding" if you must, but when I read it aloud I usually give each syllable equal emphasis. Verse length leans towards tetrameter, similar to Morning Song, but I let the words come and did not insist on making the lines the same, because morning and evening are different.
