A short story
Once upon a time there was a king.
The king wanted a painting. He'd heard about a famous painter in a distant village. "I don't care how much it costs," said the king. He sent a messenger to the painter.
"My king wants a painting," said the messenger. "Ok," said the painter, "give me two million gold coins and come back later." The messenger paid.
The messanger came back a year later. "It's not finished yet," said the painter. "Come back later."
Ten years passed.
The messenger returned. "Where is the painting for the king?"
The painter grabbed a canvas and painted a painting. "Here, give this to the king."
"What, you just made it!" said the messenger.
"Yes," said the painter, "but I've been thinking about it for ten years."
