"Yes, economy, though it seems droll to say so. In the old days, when the meat came on in a big platter, and the vegetables each in its large covered dish, people had to put more on table than was really wanted, for the sake of not looking mean and giving their neighbors occasion for talk. Now, when everything is carved on a side-table and a nice little portion carried to each person, you are able to do with exactly what is needed. There need not be a great piece of everything left over for look's sake. One chicken is enough for four or five people if it is skilfully carved, but the chicken would look rather scanty on a platter by itself; don't you think so?" "Yes," said Cannie, with a little laugh. She had forgotten her troubles in the interest of the discussion. "A dish containing one mutton-chop and a spoonful of peas for each person would be called a stingy dish in the country, where every one sees his food on the table before him," continued Mrs. Gray; "but it is quite enough for the single course it is meant to be at a city dinner. There is no use in having three or four chops left over to toughen and grow cold." "I see," said Cannie, thoughtfully; "what else did I do that was wrong, Cousin Kate?" "You called Frederic 'sir,'" replied her cousin, with a smile. "That was not wrong, but not customary. Servants are expected to say 'sir' and 'ma'am' to their employers as a mark of respect; and people not servants use the word less frequently than they formerly did. They keep such terms for elderly or distinguished persons, to whom they wish to show special deference." "But Aunt Myra always _made_ me say 'sir' and 'ma'am' to her and grandpapa. She said it was impolite not to." "She was quite right; for she and your grandfather were a great deal older than yourself, and it was only respectful to address them so. But you need not use the phrase to everybody to whom you speak." "Not to you?" "Well, I would quite as soon that in speaking to me you said, 'Yes, Cousin Kate,' as 'Yes, ma'am.' That is what I have taught my children to do. They say, 'Yes, mamma;' 'Did you call me, papa?' I like the sound of it better; but it is only a matter of taste. There is no real right or wrong involved in it." Candace sat for a moment in silence, revolving these new ideas in her mind. "Cousin Kate," she said timidly, "will you tell me when I make little mistakes, like that about the knife? I'd like to learn to do things right if I could, and if it wouldn't trouble you too much."
