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. Vanity working on a weak head produces every sort of mischief. Nothing is more deceitful than the appearance of humility. It is often only carelessness of opinion, and sometimes an indirect boast. It isn't what we say and think that defines us, but what we do.
