The same...

Author Lloyd C Douglas lived in a three story apartment building on the third floor.
Every morning he walked down to get his paper and spoke with a composer who lived on the first floor because he was confined to a wheel
chair. The man would tap his walking stick on the floor every day and tell Lloyd C Douglas, "That's Middle C" Lloyd would say, "Yes, I know. You told me yesterday and the day before."The composer said, "What do you think it will be tomorrow." Lloyd would smile and say, "Middle C" The composer would nod and say, "Just like God. He's the same yesterday, today, and tomorrow."
