Katie and her grandma often went to the gallery on their days out together. Grandma liked to tell to Katie all about the famous paintings.
"Which picture do you like best ?" asked Grandma.
"Mona Lisa", said Katie. "She smiled at me."
"She smiles at everyone," said Grandma. "That's why she is famous."
"What makes her smile?" asked Katie
"I don't know," said Grandma, resting on a chair. "Perhaps you should have a closer look at her"
"Mona Lisa by Leonardo da Vinci," said Katie, reading the notice by the painting. "I wish I knew what is making you smile."
"Then come inside, Bambina!" said Mona Lisa.
