From the Mixed-Up Files of Mrs. Basil E. Frankweiler
What happened was: they became a team, a family of two. There had been times before they ran away when they had acted like a team, but those were very different from feeling like a team. […] You might call it caring. You could even call it love. And it is very rarely, indeed, that it happens to two people at the same time—especially a brother and a sister who had always spent more time with activities than they had with each other. (3.58)
As they once again reached the back stairs, Claudia asked Jamie, "With whom shall we dine today, Sir James?"
Jamie answered, "Oh, I don't know, dear Lady Claudia. Shall we find a good and proper group?"
"Yes, let us, Sir James." (4.80-82)
He must have thought STAY PUT exactly hard enough, for Claudia did just that. They never knew exactly why she did, but she did. (5.81)
