Advice from Jane
If gratitude and esteem are good foundations of affection, Elizabeth's change of sentiment will be neither improbable nor faulty. But if otherwise--if the regard springing from such sources is unreasonable or unnatural, in comparison of what is so often described as arising on a first interview with its object, and even before two words have been exchanged,--nothing can be said in her defence, except that she had given somewhat of a trial to the latter method in her partiality for Wickham, and that its ill success might, perhaps, authorise her to seek the other less interesting mode of attachment.
So, a better way to fall in love is through gratitude and esteem rather than dazzling smiles and first impressions. In other words, nice guys ought to finish first.
