After reading through House of Mirth, I can just not get over the character of Lily. She seems to always pass up the opportunity to marry a rich man in the vain hope that an even richer man will come along. She goes from nervous to almost arrogant after meeting Gryce and deciding she wants to marry him.
The various intricacies of high society were also rather amusing to read. Stealing guests from other parties and then complaining about it later, though the large amount of gossip that seems to occur between the women seems to be a running theme in novels that involve high-class women with seemingly nothing to do but sit around and talk to one another.
