The idea of luxury, even the word "luxury," was important to Arabella. Luxury meant something that was by definition overpriced, but was so nice, so lovely, in itself that you did not mind, in fact was so lovely that the expensiveness became part of the point, part of the distinction between the people who could not afford a thing and the select few who not only could, but also understood the desirability of paying so much for it. Arabella knew that there were thoughtlessly rich people who could afford everything; she didn't see herself as one of them but instead as one of an elite who both knew what money meant and could afford the things they wanted; and the knowledge of what money meant gave the drama of high prices a special piquancy. She loved expensive things because she knew what their expensiveness meant. She had a complete understanding of the signifiers.
Freedom is an expensive gift always worth fighting for. Even if it costs us!
