Barbara in Brittany

Barbara entered the nursery with rather a worried look on her face. Aunt Anne is coming to-morrow, children, she announced.
To-morrow! exclaimed a fair-haired boy, rising from the window-seat. Oh, I say, Barbe, that's really rather hard lines—in the holidays, too.
Just as we were preparing to have a really exciting time, sighed Frances, who was her brother's close companion and ally.
I know it's a little hard, Barbara said consolingly, sitting down beside them and taking one of the twins on her lap, while the other leaned up against her. But you will all try to be good and nice to her, won't you? She went away with a bad opinion of us last time, and it worries mother. Besides, we mustn't forget that she was father's sister.
I can't think how she ever came to be, sighed Frances. She's so dreadfully particular, and we always seem naughtier when she's here. But we'll make an effort, Barbara.
And you won't run away as soon as she speaks to you, Lucy? Barbara went on, looking at the little girl in her lap. It's rude, you know. You must try to talk nicely when she wants you to.
Yes; and the child nodded. Only she does seem to make a lot of concussions when she comes.
You mean discussions, Donald corrected. You shouldn't use words you don't understand, Lucy. But I must say I agree with you; I know she always raises my corruption.
