David's declaration is fumbling and comical; he describes himself as "raving," and Jip's incessant barking gives the scene a sense of slapstick humor. Interestingly, David's account also skips over the actual proposal, perhaps implying that he wasn't in his senses at the time and consequently doesn't remember it. What's more, he remarks that neither he nor Dora was really thinking of marriage in a serious way at the time. All of this highlights the fact that David's decision to marry Dora is not a measured and thoughtful one; in fact, it's hardly a conscious decision at all.
