Of Human Bondage by William Somerset Maugham

Christmas that year falling on Thursday, the shop was to close for four days: Philip wrote to his uncle asking whether it would be convenient for him to spend the holidays at the vicarage. He received an answer from Mrs. Foster, saying that Mr. Carey was not well enough to write himself, but wished to see his nephew and would be glad if he came down. She met Philip at the door, and when she shook hands with him, said:

"You'll find him changed since you was here last, sir; but you'll pretend you don't notice anything, won't you, sir? He's that nervous about himself."
