On friendship

I am reading The History of Tom Jones, a foundling by Henry Fielding. It's a lot of fun, in an 18th Century sort of way. Full of witty quotes. I just ran across this one, though, which I really like.

I hope my friends will pardon me when I declare, I know none of them without a fault; and I should be sorry if I could imagine I had any friend who could not see mine. Forgiveness of this kind we give and demand in turn. It is an exercise of friendship, and perhaps none of the least pleasant.

Yes, indeed.
