I couldn't figure out what to say about this song. For like, two months. Because you probably think this song is about you.
Seriously, I made the mistake of posting these lyrics somewhere online in my LiveJournal days (ancient history!) and the subject knew instantly the song was about him. But since it's sort about everyone who's ever been in my life, it wasn't that much of a stretch.
Some free advice: even though it feels natural to repeat your mistakes, you're actually supposed to learn from them.
