A classic! I always loved this particular line of the song because it's almost like there is this constant argument between two people and still, with all the fighting and disagreement, there is still this feeling of understanding beyond. Like, it doesn't really matter what you say, because I'll get it anyway. Even when I really don't, somewhere deep inside I do know. And on another note, this song is like almost perfect with the whole divorce deal they are having with Avril Lavigne.
