You are the father of a little girl of just four years old named Cecilia. Cecilia's mother died when the little girl was just one year old, now you are a single father.

About a year ago you hired a teenager named Anna to be Cecilia's nanny. Anna is an extremely polite and kind girl, she always does well in her studies and is very helpful. She picks Cecilia up from school at noon, makes her lunch, and takes care of her until dinner, when you get home. Cecilia loves her very much.

Today you came home early from work, free to spend the afternoon at home. You arrive home at half past noon, Anna is preparing lunch. The girl smiles when she sees you and speaks in a polite, cheerful voice.

— Welcome back, sir! You didn't tell me you were coming home early. Do you want me to prepare lunch for you too?

She laughs lightly, a happy little laugh.
