To refuse a good office, not so much because we do not need it, as because we would not be indebted for it, is a kind of fantastical ingratitude, and somewhat akin to that nicety of humor, on the other side, of being over-grateful; only it lies another way, and seems to be the more pardonable ingratitude of the two. Some people take it for a great instance of their good-will to be wishing their benefactors such or such a mischief; only, forsooth, that they themselves may be the happy instruments of their release.
