A man calls for wine from his bed, and a woman will not let him come to her. Dave Bonta tells the whole event in eight short lines and one sentence. The poem is built around a swerve in its last three lines, where the rival turns out to be a drink and not a person. By the end, a bedroom quarrel has become a small portrait of what people reach for when they want protection, and of what that does to the people who love them.
The syntax carries the trick. Everything before "out of jealousy" suggests an ordinary love triangle, and the reader expects a third person to appear. Then comes "of that other", a phrase that sounds like a human rival, vague and a little sneering, the way one might refer to an unnamed mistress. The line break is clever, because "between him" makes us picture someone standing between husband and wife, or between lover and lover. Only "and trouble" completes the thought and changes the picture. The other stands between him and trouble. The wine is a shield, and it is also a third presence in the room. The poem never names the trouble, which makes it feel larger. It could be grief, worry, or just the day. What matters is that he has found something that will stand guard for him, and she has not been asked.
That is where the jealousy gets interesting. She may resent the wine for coming between them, but the poem's wording suggests something sadder. The wine does the job she might have wanted, putting itself between him and his troubles, and he trusts it more readily than he trusts her. Her refusal also reverses the power in the first lines. He "sent for" the wine, which sounds like someone who stays put and has comfort brought to him. She, by contrast, "would not let him", so she is the one who finally decides. That refusal is her only move, and it is a small and painful one.
The form is as spare as the story. There is no rhyme and almost no punctuation, just one comma after "bed" and a full stop at the end. The lines are short, mostly three or four syllables, with about two stresses each, so the poem moves in little breaths. Without punctuation, the sentence tumbles from line to line, and nearly every break tempts us to read ahead and then corrects us. "Would not let him / come to her" is a good example. Taken alone, "come to her" can sound like simple approach, or something more intimate, and the poem lets both possibilities sit there. Some quiet sound-play holds the lines together. The short "e" of "sent", "bed", "let" and "jealousy" recurs like a low knock, and "her" and "other" share an ending that ties the woman to the rival she resents. The last line, "and trouble", ends on a soft, unstressed syllable. The poem trails off the way a worry does.
The title is just as important. A "nightcap" is a last drink before sleep, a word that sounds homely and harmless, even cosy. Bonta never says that the man drinks too much, and he does not need to. The poem gives us only the request and the refusal, so the cosy word and the woman's jealousy pull against each other. A cap also covers something, which fits the way the wine is meant to close the day off from its troubles. That second sense is a reading, not something the poem insists on.
What makes the poem worth remembering is how much it leaves out. There are no names, no setting beyond "bed", and no explanation of the trouble. Its few nouns are wine, bed and trouble, and its pronouns, "he", "she", "him", "her", carry nearly all the feeling. The compression makes the reader do the work of imagining the rest. Is she angry, hurt, or afraid? Is he careless, or simply worn out? The poem refuses to say, and that restraint is its strength. In eight lines it shows how a drink can be treated as a person, and how someone who feels shut out by a glass can end up shutting the door herself.
