Peace of Mind

I solve problems at work all day Sort through all the rubble By the time I leave there’s not much left Of my mind and that’s the trouble My mouth keeps moving it gives the impression That I know what I am saying But my brain shut down hours ago And the rest of me is just delaying Sometimes people don’t notice- They think I know what is coming out I actually don’t have a clue And really there’s no reason to shout Eventually I have to give in And I take myself to bed Tomorrow when my brain shuts down I’ll just talk to myself instead
