Jessea L. Vaughan's speaker starts with the big questions: why the world turns, why time passes, why people and even dogs exist. Each time, the answer is the same shrug: "I haven't a clue." The tone is casual and a little amused rather than anxious, as if the speaker is chatting about mysteries too large to solve.
What puzzles the speaker most is the odd mix in things. They seem "simple and clear" and yet "illogical / And random." There's also the strange fact that we wonder why things are this way at all, rather than some other way.
The ending is the funniest and most honest part. The speaker admits not knowing what else to say, or why they wrote anything. The poem folds its confusion back on itself, so even the act of writing becomes one more thing without a reason. The mood is humble, wry, and gently playful, with a quiet wonder underneath.
