How does Oscar Wilde mock Victorian society in "The Nightingale and the Rose?"

In "The Nightingale and the Rose," Wilde mocks several aspects of Victorian society. Firstly, through the character of the girl, Wilde satirises contemporary courtship rituals and conceptions of love. That she will only accept a red rose, for example, demonstrates the shallow and materialistic understanding of love among young people of the Victorian middle class. Similarly, Wilde further mocks the middle class when the girl refuses the red rose, on the grounds that it does not match her dress. 

Secondly, Wilde satirises Victorian society when the Nightingale sings of her pending sacrifice to the student. We see this most clearly in the following lines:

The student could not understand what the Nightingale was saying to him, for he only knew the things that were written down in books.

In this example, Wilde mocks the Victorian definition of knowledge and suggests that true knowledge and understanding comes from the everyday world, not just academic books. Had the student grasped this idea, he would have realised the Nightingale's sacrifice and, in turn, understood the real meaning of love.
