At the end of Gatsby when Tom and Nick meet, after their conversation Nick states that Tom:
"went into the jewelry store to buy a pearl necklace — or perhaps only a pair of cuff buttons — rid of my provincial squeamishness forever."
I have a few questions:
Why didn't Nick tell Tom it was Daisy, not Gatsby in the car. (and does Tom already know that)?
Why does Nick say he is: (My friend told me it has something to do with character but I don't understand it)
"rid of my [his] provincial squeamishness forever."
What is the significance of Tom walking into a jewelry store?
