Answer:
These lines help to develop the plot of mistrust and amenity among friends.
Explanation:
These lines were spoken by Señora. She is portrayed to be one of the main characters of this story along with Rosaura and Luciana.
Luciana decides to hold a party at her home and invites Rosaura. She is a nine-year-old year who thinks that Luciana is her friend, but little did she know that Luciana had ulterior motives.
She only invited Rosaura so she could make her do the work and help Senora. Rosaura's mother tried to stop her from going to the party but she did not listen.
