Certainly a good friend isn't always thinking of that; one doesn't suspect one's friends of injustice.

I don't suspect you, my dear, in the least; but I suspect human nature.

Don't think I make myself uncomfortable; I'm not always watching myself.

I think I sufficiently prove it in talking to you as I do now.

All I wish to say is, however, that if you were to be jealous--that's the form it would take--I should be sure to think it was a little my fault.
