Dave Bonta's tiny poem is about the pleasure of evening, and it gets there through the idea of appetite. Night is first called "a welcome wine," something you take in and are warmed by, and then "a great carcass," a huge body of meat laid out to be eaten. The two images sit oddly together: one is refined, the other almost primal. That mix suggests a speaker who enjoys both the gentle and the raw sides of darkness.
The title, "Bon vivant," means someone who loves good living, and the speaker fits it. Coming "home to supper," he is "red as a bee," a strange, vivid comparison. Judging by the imagery, the redness may come from wine, warmth, or a day spent outdoors, though bees aren't usually red, which adds a playful, slightly dreamlike touch. The mood is contented, sensual, and a little humorous. Night isn't something to fear here. It's something to be consumed and enjoyed.
