Weak people cannot be sincere.
However greatly we distrust the sincerity of those we converse with, yet still we think they tell more truth to us than to anyone else.
The boldest stroke and best act of friendship is not to disclose our own failings to a friend, but to show him his own.
The reason we do not let our friends see the very bottom of our hearts is not so much distrust of them as distrust of ourselves.
It is with sincere affection or friendship as with ghosts and apparitions,--a thing that everybody talks of, and scarce any hath seen.
