In just three lines, this haiku-like poem captures a small, sharp moment of loneliness. The speaker is lying in bed, alone, when a long call breaks into the night. The poem doesn't say what makes it. It could be a bird, an animal, or something else entirely, and that vagueness lets us hear it the way the speaker does, as a sound with no clear source.
What matters most is what comes next: "the sudden nothing after." The call is brief, but the silence it leaves behind feels bigger than the sound itself. Before the call, the house may have seemed simply quiet. Afterward, the quiet becomes noticeable, almost heavy, because something has interrupted it and then vanished.
The final line, "alone in bed," lands plainly, with no explanation. The speaker seems to feel their solitude more strongly now, as though the call briefly offered company or a sign of life and then took it away. The mood is hushed, still, and a little wistful, built from very little.
