couldn't find her new shoes; and at last she discovered that the other had been wearing them every other day, so as to keep 'em even, so that they could keep on getting new shoes at the same time.
And sometimes they had to answer the doorbell when the maid was away, and by and by one of them found out that when her sister answered the bell, if she had on her good clothes, she said that she was herself, but if she was the least bit untidy, she said that she was her sister; and so the sister got the reputation of being always untidy, and the other of being always nice and trim.
Her sister got even with her, though, by telling all the girls in school that she was the one that she wasn't, and that she was going to wear a little green bow on her sleeve, so that they could know her from the other; and then she wore her oldest clothes, and soiled her face and hands and missed her lessons and roughed her hair all up for a week, before the other one found out what she was doing.
They never got angry at each other, though,—they didn't seem to know how to. I think it must have been because they felt so much like one person.
