"Now we'll have an examination; it'll be good practice for you."
He put a question, and she answered it, frowning a little.
"H'm. That's not very good, my dear."

"It's no use, Jimmy. My head's hopeless this afternoon. Another time."
He shut the book.
"Yes. So it seems.... You're overdoing it, Neville. You can't go on like this."
She lay back and spread out her hands hopelessly.
"But I must go on like this if I'm ever going to get through my exams."
"You're not going to, old thing. You're quite obviously unfitted to. It's not your job any more. It's absurd to try; really it is."
