From George Eliot, “Middlemarch”

This was not the first time that Mr. Bulstrode had begun by admonishing Mr. Vincy, and had ended by seeing a very unsatisfactory reflection of himself in the coarse unflattering mirror which that manufacturer’s mind presented to the subtler lights and shadows of his fellow-men; and perhaps his experience ought to have warned him how the scene would end. But a full-fed fountain will be generous with its waters even in the rain, when they are worse than useless; and a fine fount of admonition is apt to be equally irrepressible.
