The poem is presented in a rambling yet rhythmic free verse whose lines are of fairly even length in size and feet. The first line declares the first person singular, presumably the poet, to be "an important person," at least to feeder birds--a humorous opening. The poet contrasts the newness of those anticipating their first anniversary with the "sagging" of those anticipating their thirty ninth. The relatively newlyweds look with a jealous eye at the familiarity of the old married couple. The older couple looks with jealousy at their younger counterparts for whom everything is a "first" and for whom everything holds the excitement of discovery.
