"Why?"

"Oh, for a lot of reasons I can't talk about."

"I don't have to explain that, do I?"

"No, I suppose not." She hoped he was going to drop the subject, when he lifted his head to look at her with his rather pathetic blue eyes, "Oh, but I say, you're not serious in thinking you wouldn't, are you?"

"Perfectly serious. I should never look on the matter as admitting discussion."

"Oh, but it does, you know."

"Not for me."
