Lyric discussion by Serglethal 

Cover art for Time Bomb lyrics by Dave Matthews Band

This is about Dave having to deal with the murder of his sister by her husband who then turned the gun on himself

"no one would ever believe it, He was such a normal man"

And also dealing with his disbelief in "God" and wanting and answer from him about why he would let such a horrible thing happen to anybody, specially his own sister.

Peace
