Aunt Polly asked him questions that were full of guile, and very deep—for she wanted to trap him into damaging revealments. Like many other simple-hearted souls, it was her pet vanity to believe she was endowed with a talent for dark and mysterious diplomacy, and she loved to contemplate her most transparent devices as marvels of low cunning.

Middlemarch

"Vanity and pride are different things, though the words are often used synonymously.  A person may be proud without being vain.  Pride relates more to our opinion of ourselves, vanity to what we would have others think of us."
