It was noon, and John Brown accompanied Charlotte Grandy and her parents to lunch. Charlotte's chatty little mouth didn't stop talking, and she looked incredibly cheerful. Her parents, all smiles as they talked to her, appeared to be a picture-perfect, loving family of three from the perspective of outsiders.
However, when Charlotte went into the exam hall again in the afternoon, her parents reverted to acting like strangers. Several times, Charlotte's mother seemed as if she wanted to say something to John, but ultimately held back.
