In the book "Desolation Island," a humorous exchange highlights the protagonist Killick's casual approach to marriage. He reassures a concerned figure about his decision, stating he has pondered the matter seriously for a whole twenty minutes. This tongue-in-cheek remark illustrates his lighthearted attitude towards a significant commitment that typically requires much more deliberation.

The dialogue also underscores the motif of choosing among options, as Killick mentions having three prospects to consider. His pride in selecting what he believes to be the best choice reflects both his enthusiasm and the often trivial manner in which such life-altering decisions can be treated, adding a layer of irony to the gravity of matrimony.
