“What’s wrong?” said the tutor.

“Oh, nothing; only I don’t feel particularly festive. I’ve been lying awake a long time.”

“Pity you didn’t get up. Shocking habit to lie in bed after you’re awake.”

“At that rate I should often be up at two in the morning,” said Roger.

“I doubt it—but what’s wrong?”

Roger put down his brush, and flung himself on a chair.

“I don’t know—yes, I do. Can’t you guess?”

“Cheese for supper,” suggested the tutor seriously.

“Don’t be a fool, Armstrong, and don’t laugh at me; I’m not in the mood for a joke. You know what it is well enough.”

The tutor’s glass dropped from his eye, and he walked over to the window.
