Written as a message to someone who has drifted away, this is a poem about loneliness after a close connection breaks. The speaker says they feel so alone it's a wonder they're still alive, and that line sets a raw, honest tone. They remember long conversations, "endless paragraphs," that seemed like they would go on forever, until they hit "a full stop." The punctuation image is simple but effective: the friendship, or relationship, simply ended.
Each time the phone buzzes, hope turns into disappointment because it isn't the other person. The speaker calls themselves a fool for believing things might return to how they were, which shows how much they're blaming themselves.
The ending changes the mood. After hoping the message "finds you well," the speaker admits what they really wanted to say: "I'm scared." Set alone on its own line, it feels quiet and exposed, as if all the earlier pain was leading up to this one confession.
