The marriage and sexual politics in this book continue to be very oddly soap-operalike and filmic to me. Or at least, the characters want their sex lives/marriages to be like a film.
Remember the part we discussed in class about Nick confronting Marian about her closeness with Brian? He wished he'd stood at the door so he could say something ominous about the potential affair and then walk away.... as if he wanted to make their marriage to play out like a drama. Nick wants to perfect the theatrics of domestic life.
Well it seems his brother is trying to do the same with Janet before their marriage, hoping she'll ask him to leave her job and get married.
