“Well,” said she to herself, “this is most strange! – After I had got him off so well, to chuse to go into company, and leave Harriet ill behind! – Most strange indeed! – But there is, I believe, in many men, especially single men, such an inclination – such a passion for dining out – a dinner engagement is so high in the class of their pleasures, their employments, their dignities, almost their duties, that anything gives way to it – and this must be the case with Mr. Elton; a most valuable, amiable, pleasing young man undoubtedly, and very much in love with Harriet; but still, he cannot refuse an invitation, he must dine out wherever he is asked. What a strange thing love is! he can see ready wit in Harriet, but will not dine alone for her.”
– Jane Austen
Emma, Chapter 13. We see Austen’s use of ironic humor and Emma’s propensity for misperception and self-deception when Emma talks of Mr. Elton’s strange behavior towards Harriet. Strange for Emma, because she mistakenly believes that she has made a love match for Harriet with Mr. Elton. But the audience knows that he is more interested in Emma than her friend. And she is too blind to see this.
