    "You set your heart too much on things, Anne," said
    Marilla with a sigh. "I'm afraid there'll be a great many
    disappointments in store for you through life."
    "Oh, Marilla, looking forward to things is half the
    pleasure in them," exclaimed Anne. "You mayn't get the
    things themselves; but nothing can prevent you from having
    the fun of looking forward to them."
