Here is the text:
I shall never forget the day she told me that there was to be a ball at Keverall Court.
"Of course a young lady in my daughter's position must be brought out formally. I am sure you realize that, Miss Osmond, because although you yourself are not in the same position, you did learn something of gracious living when you were allowed to take lessons here."
"Graciousness is something that I miss nowadays," I retorted.
She misunderstood. "You were very fortunate to be allowed to glimpse it for a while. I always think it is a mistake to educate people beyond their stations."
"Sometimes," I said, "it enables the sons and daughters of erudite churchmen to be of use to their betters."
"I am glad to see you take that view, Miss Osmond. I have to confess you do not always show such becoming humility."
