Priscilla's "Stranger" is about the quiet shock of realizing that someone close to you no longer feels like the same person. The speaker misses a friend, and perhaps someone more than a friend, during a few days apart. When he returns without a word, she is hurt and left wondering why she is the one reaching out. Still, she gathers her courage and sends a simple "Hey."
What follows is a conversation that feels wrong. His wording, his typing style, even the rhythm of the exchange seem off. The short, broken lines mirror her hesitation and growing unease, and the quotation marks around "talk" suggest the exchange hardly counts as real conversation. The mood moves from longing to doubt to fear. The ending is blunt and cold: the person she loved has been replaced, in her eyes, by "a stranger." The poem leaves us with the sadness of losing someone without any goodbye.
