The document appears to be lyrics from the song "I Knew You Were Trouble" by Taylor Swift. It describes a relationship that has gone wrong, with three key events: 1) The narrator falls hard for their partner but their partner takes a step back, highlighting Andrew Goodwin's theory. 2) The partner sweeps the narrator off their feet, taking them to new places, until ultimately letting them down. 3) Now, the narrator finds themselves lying alone on the cold ground, having realized that their partner was trouble all along.
