John D．Rocke feller， the wellkn own millionaire，gave away millions， but he himself was very mean about small sums of money． One day he went to stay at a hotel in New York and asked for the cheapest room in it． He said，I am staying here alone and only need a small room．
The manager showed him into a room and said，This is our smallest and cheapest room， and added，but why do you choose a poor room like this？ When your son stays here， he always has our most expensive room ；yours is our cheapest．
Oh！ yes，said Rockefeller，but his father is a rich man；mine isn't．
