It is Saturday. Mr and Mrs Frost are shopping at their local supermarket. Rosa is alone for the first time with Elisabeth and Isaac. They are in the living-room. The two Frost children are sitting in front of the television. They are watching a Tom and Jerry cartoon. Tom is a cat and Jerry is a mouse. The mouse is very intelligent and gives the cat a difficult time. The cartoon is popular in many countries and Rosa often watches it in Spain, but she is not watching it with the children.

 Rosa is taking some coloured crayons and some paper from a plastic bag. First, she draws a picture of her English family's kitchen. She then draws Tom and Jerry. Tom the cat is on the kitchen table and Jerry is under it. The mouse is drinking the cat's milk. Soon Elisabeth and Isaac are looking at Rosa's picture. Rosa is very happy because she has the two English children's attention. She quickly takes some coloured paper from her bag. The paper is for Japanese Origami.

 "What are you doing?" Elisabeth asks.

 "Watch me and you'll see!" she says.

 Soon the children are drawing their own pictures and playing with paper models of Tom and Jerry.

 Later that morning, Mr & Mrs Frost arrive home. They are very happy to see their children together with the young lady from Spain.

 "What a surprise!" Mr Frost says. "The children usually watch television all the morning, but now you have their full attention. How do you do it? Do you have a Spanish secret?"

 "Your children don't understand Spanish and I don't have any secrets", says Rosa modestly. She does not tell them about the big, black book. In the evening, Rosa phones her mother in Madrid. Maruja is glad to hear that her daughter is safe and well. Rosa is happy to tell Maruja about English children, Tom & Jerry and international psychology.
