In the short story "The Stolen Party" by Liliana Heker, a girl named Rosaura is invited to her friend Luciana's birthday party. At first Rosaura's mother is incredulous; she is the maid in the home of Luciana's parents, and Rosaura only knows Luciana because she goes over and does homework with her while Rosaura's mother is cleaning. Rosaura's mother proclaims that it is a "rich people's party" and that Rosaura is known only as "the maid's daughter." We see here a clash of cultures between rich people and the poor people who provide services for them. However, Luciana seems to have invited Rosaura in sincerity, and Rosaura's mother eventually allows her to go.
Apart from an encounter with a snobby cousin of Luciana's, Rosaura has fun at the party. She doesn't think anything of it when Senora Ines, Luciana's mother, continually asks her to help with serving food and drinks. She is fully convinced that she is there as one of the guests until the end, when she and her mother are leaving. Then she is emotionally crushed when Senora Ines offers her money instead of one of the party gifts that the other children have received.
There are two main themes in this story. One of them is the loss of innocence of the protagonist, Rosaura. She believes that she has been invited to the party as an equal to the other guests, and it's possible that Luciana intended this when she extended the invitation. Being treating like an inferior by Luciana's mother, as hired help instead of as a playmate and friend of Luciana, shows Rosaura that there is a social gap between rich and poor that is exceedingly difficult to bridge.
Another theme that accompanies the theme of Rosaura's loss of innocence is the evil of cultural or class distinctions. The difference between rich and poor and the behavior of people according to their status is accepted by the adults. However, the hurt that Rosaura feels at the end of the story shows how wrong these distinctions are.
