"I don't think you trust, in, my, self-righteous." Is saying that his friends/loved ones are not believing that his decision is a good decision, but a bad one. "I cry, when angels deserve to die." I believe this comes from the point of view of his friends/loved ones saying that because he seemed perfect (like a angel) nothing bad will ever happen to him. He has had a perfect life, nothing bad has ever happened to him. So when he commits suicide they cry because of the simple thought, how can a angel die? So all in all my interpretation of the song is that a guy bottles up his pain and hides his scars from the shake up (fight, mentally or physically) and commits suicide. Leaving everyone else who thought that he was a angel to cry in disbelief or agony. (disclaimer- members of System has stated that we make our own meanings. Saying that although my theory may not be correct, it is not incorrect either.)

The meaning of this song is talking about a misunderstood person. "Grab a brush and put on a little makeup." Is talking about a person covering up his wounds to appear as if normal. "Why'd you leave the keys up on the table" Is showing that he doesn't care if anyone comes into his house anymore since he is soon to die.
