"By the way, Mr. Gatsby, I understand you’re an Oxford man."
"Oh, yes, I understand you went to Oxford."
"Yes – I went there."
Pause. Then Tom’s voice, incredulous and insulting: "You must have gone there about the time Biloxi went to New Haven."
Another pause. A waiter knocked and came in with crushed mint and ice but, the silence was unbroken by his "thank you." and the soft closing of the door. This tremendous detail was to be cleared up at last.
"I told you I went there," said Gatsby.
"I heard you, but I’d like to know when."
"It was in nineteen-nineteen, I only stayed five months. That’s why I can’t really call myself an Oxford man."
Tom glanced around to see if we mirrored his unbelief. But we were all looking at Gatsby.
"It was an opportunity they gave to some of the officers after the Armistice," he continued. "We could go to any of the universities in England or France."
I wanted to get up and slap him on the back. I had one of those renewals of complete faith in him that I’d experienced before. (7.208-221)
