The poem begins with a pleasant evening: dinner, a play, and "mad love." It sounds like a perfect night out. But in the second stanza the mood shifts. Once the evening is over, the speaker's mind turns to large, slightly dizzy questions: "who to be / whom to happen to." Identity here feels less like a choice and more like something that simply happens to you, and the odd grammar of the phrase makes that uncertainty feel real.
The last stanza adds a wry note. "Zen in new clothes" suggests that the calm, accepting attitude the speaker is reaching for might be an old idea dressed up to look fresh. Then comes the plain question: "are we content?" It's left unanswered. The mood is quiet and thoughtful, a little playful, and a little unsettled. Happiness and doubt sit side by side, and the poem seems to say that even a lovely night can leave you wondering what it all means.
