It is Saturday afternoon and the Santos family is very busy. Tonight, they are celebrating a special birthday — it is Avó Rosa's 70th birthday. Avó Rosa is the grandmother. She does not know about the party. She thinks the family is just having a quiet dinner together.
Paulo is the father. Usually, he reads the newspaper in the garden on Saturday afternoons. Today, he is not reading. He is hanging colourful balloons in the garden and is decorating the fence with lights. He is working very hard.
Luisa, the mother, is in the kitchen. She usually bakes simple cakes at the weekend, but today she is trying a new chocolate recipe. It smells wonderful. She is checking the oven every few minutes.
Marco is their sixteen-year-old son. He usually spends Saturday afternoons in his room listening to music. Today, he is not in his room. He is helping his father in the garden and is carrying boxes of decorations outside.
The twins, Ana and Pedro, are nine years old. They usually watch TV after lunch. This afternoon, they are not watching TV. They are sitting at the kitchen table and are making a big birthday card for their grandmother. They are being very quiet and careful.
The dog, Bolinha, is running around the house excitedly. He does not understand what is happening, but he knows something special is coming.
