So yea this song was made not for the movie twilight at least the meaning has nothing to do with the book in general it has to do with guys in general its saying that she used to be so close to this guy that she loved alot and then he just changed and she wants to get into his head but the truth isn't in his head and its like when you look him in the eyes you can tell what kind of person he is and her thoughts he just can't understand and she needs to figure things out on her own n like the song can have any meaning but if your tlking about real life that's basically the whole song sumed up in one paragraph and if your tlkin about twlight then crzygrl210 summed it up but I think that if you listen to every song paramore has ever written its basically related to this song and I think hayley wrote it about a relationship gone bad but she could use her idea using the book as well so not only does it tie in with the book twilight but it also can tie in with real life I mean many girls can relate to this song n you can't forget g** guys I mean I kno I'm no expert in finding out what she thought but I mean this is my form of ocd so I find the meaning in songs when ever I listen to a song but this is my opinion and many of you might agree with me but I mean everyone has a different opinion and I just happened to have expresed mines I'm not sayin I'm right and I'm not saying any of you is wrong I just said what I thought it meant.
