Laura has no false modesty, does she? ;-) In addition to her description of her manifold talents and accomplishments, she compares so favorably to all other women she meets!

Her dear friend, Isabella is described to her own daughter Marianne thus:

Tho' pleasing both in her Person and Manners, (between ourselves) she never possessed the hundredth part of my Beauty or Accomplishments. (letter 4)

No, of course not. Edward's sister Augusta displayed

...none of that interesting Sensibility or amiable Simpathy in her manners and Address to me when we first met, which should have Distinguished our introduction to each other. Her Language was neither warm nor affectionate, her expressions of regard were neither animated nor cordial; her arms were not opened to receive me to her Heart, tho' my own were extended to press her to mine. (letter 7)

And Dorothea, her husband's former intended:

I soon perceived that tho' Lovely and Elegant in her Person, and tho' Easy and Polite in her Address, she was of that Inferior order of Beings with regard to Delicate Feeling, tender Sentiments, and refined Sensibility (letter 7)

Quite unlike her own quite refined sensiblity, I'm sure! Janetta might have shown promise, but alas, her father

...had actually so far extinguished the natural noble Sensibility of her Heart, as to prevail on her to accept an offer from a young Man of his Recommendation. (letter 12)

Oh, we can't have that. And then there is the widow's daughter:

...who was then just seventeen -- One of the best of ages; but alas! she was very plain and her name was Bridget... Nothing, therefore, could be expected from her -- she could not be supposed to possess either exalted Ideas, Delicate Feelings or refined Sensibilities. -- She was nothing more than a mere good-tempered, civil and obliging Young Woman; as such we could scarcely dislike her -- she was only an Object of Contempt. (letter 13)

Only Sophia compares favorably to Laura:

Sophia was rather above the middle size; most elegantly formed. A soft languor spread over her lovely features, but increased their Beauty. -- It was the Characteristic of her Mind. -- She was all Sensibility and Feeling. We flew into each other's arms. (letter 8)
