Lyric discussion by uploadnil 

I think the title "I Threw a Brick Through a Window" is pretty interesting too. When I first saw it and heard the song I wondered how it went with the lyrics, so I have several theories. Both go along with what Bayoustorm and eirenightshade said.

The title might refer to something bad he did recently - in this case throwing a brick through someone's window - that led him into a negative lifestyle he's now trying to get out of. Bono would maybe be writing from the perspective of a teenager who fell into the wrong crowd, despite warnings from people around him. "He was my brother" hints to me that his brother or someone else important to him persuaded him to do what he did, and "Be my brother" indicates that he wants the person he's singing to to take on the role of an influential 'brother figure' and pull him out of this bad lifestyle.

Another theory I have has to do with the lines, "I walk into a window to see myself and my reflection When I thought about it, my direction Going nowhere, going nowhere." If this window showing his reflection is the window the title refers to, then I think he threw the brick through it because he was frustrated with himself and how he's "going nowhere." He wants to change but doesn't know how, which is why he says "be my brother," and "There is another way out of here, In my Brother" indicating that he wants someone to help him change.
