If a friend tell thee a fault, imagine always that he telleth thee not the whole.

He that would live in peace and at ease, must not speak all he knows nor judge all he sees.

The possession of a strong will and a clever head makes some things very difficult to see

What is your friend: the things you know, or the things you don't know. First of all, there's a lot more things you don't know. And second, the things you don't know is the birthplace of all your new knowledge! So if you make the things you don't know your friend, rather than the things you know, well then you're always on a quest in a sense. You're always looking for new information in the off chance that somebody who doesn't agree with you will tell you something you couldn't have figured out on your own! It's a completely different way of looking at the world. It's the antithesis of opinionated.

Be stingy of nothing but the name of friend, and take care not to waste your insults.

...or like an old friend one has known too well and doesn't want to see.

It takes considerable effort to see facts (and remember them) while withholding judgment and resisting explanations.

Let him be wise, or let me be blind; don't let me, she hoped concretely, don't let me know too surely what he thinks of me.

The greatest effort of friendship is not to show our faults to a friend, but to show him his own.

I am slow to listen to criminations among friends, and never expose their quarrels on either side…allow bygones to be bygones, and look to the present & future only.

A man who looks to his friends for help will take his time about a thing.

It is true that I have thought more and that my daydreams are more extended and magnificent, but they want (as the painters call it) KEEPING; and I greatly need a friend who would have sense enough not to despise me as romantic, and affection enough for me to endeavour to regulate my mind.

All no means is they don’t know for sure or there’s a secret being kept, like someone’s trying to hide something really good.

"Be slow in choosing a friend, slower in changing. There are three faithful friends in our life,an old wife,an old dog and ready money. A real friend is one who always warms you.
"Love is blind. Friendship close it eyes.
