Name two examples of Gatsby's behavior before Daisy's arrival.
He sends flowers. He gets Nick's lawn mowed. Despite the preparations, he becomes absent-minded about them ("'What grass?'"). He offers Nick a business connection. He becomes upset that she is late even though there are two minutes left until the time agreed upon.
Why did Daisy cry before her bridal dinner?
She received a letter -- we can infer it came from Gatsby.
What complaint does Nick have against Gatsby that he confronts him about?
Nick says he does not like mysteries. He can't understand why Gatsby won't be straightforward and tell him what he wants and instead asks through Jordan.
