Definitely a song about a past love who comes out of nowhere one day, years after having last spoken, when he's moved on, and she tears his world back down a little bit, because it throws him back into thoughts of things he thought he'd buried for good. A feeling of confusion that ruins his day, wondering why the hell she decided to contact him after all this time. Wondering what the point is, etc. It's like she doesn't -want- him to move on.
