Which quote and page (it can be a description, a dialog or one of Nick Carraway’s reflections) that represents a social reality?

Society didn't care that Tom had a mistress. They just didn't want to see her. He could do whatever he wanted, as long as he didn't flaunt it.

The fact that he had one [a mistress] was insisted upon wherever he was known. His acquaintances resented the fact that he turned up in popular restaurants with her and, leaving her at a table, sauntered about, chatting with whomever he knew.
