Pulled Pin

I cannot recall exactly when it occurred, but somewhere along the line, the hand grenade that is housed in my skull had its pin pulled. I suppose that the pressure produced by the activity of my brain has held the handle in place thus far. I suppose that it is still there preventing the delayed fuse from becoming delayed no more. The more and more I walk around, the more and more I feel it rattling around wanting to come free, wanting to do what it was intended to do. With each dead face that passes me by the threat is high, for their indifference and lack of attention makes my brain shake and roll about. Nobody knows that just behind my eyes is a very high explosive. Nobody cares. Why should they?
