How does the Christmas scene on pg. 263 reveal the role reversal between father and daughter? What conflict does it bring up for Jeannette?

Rex returns to New York City at Rose Mary's request and spends that Christmas with his family. When Jeannette tells her father she may have to drop out of Barnard because she is $1,000 dollars short of tuition money, Rex produces $950 of earnings from poker games and tells her to use it towards school. Jeannette says that they need the money more than she does but her parents insist that she take it.
