"You don't know him, Frank."
"How did you discover he was drinking?"
"How? Why, I can tell as soon as he takes the first glass. I can always tell. There is that in his manner, his voice, his eyes, that tells me."
"But he thinks you do not know."
"Yes, yes, he thinks so."
"You have kept it from him."
"Poor pop! I let him think he is fooling me."
