Dave Bonta's "Besitted" puts the speaker in a strange, quiet spot: the garden of his own desire, where he sits beside a cloud. A garden usually suggests growth and pleasure, so you might expect something lush. Instead, the company he keeps is heavy and still.
The three comparisons in the last lines do most of the work. The cloud is "heavy as a church," "as an office," "as a quiet fool." A church and an office are both places with rules and weight, one sacred and one routine, and the fool is the odd one out, silent and a little pitiful. The title, a play on "besotted," hints at being infatuated or foolishly smitten, so the speaker may be the fool himself. The poem suggests that wanting something can leave you sitting still, weighed down, rather than moving toward it. The mood is hushed, wry, and faintly gloomy, with a touch of self-mockery.
