She is not materialistic and does not like spending money on luxurious items, telling Edward in New Moon "not to spend a dime on birthday," and that fast cars are unnecessary, saying that Edward gave her himself and anything else he gives her would throw their relationship off balance.
她不是物質主義的人，也不喜歡花錢在奢侈品上，因為她指出愛德華在《新月》時「在我的生日上不花一分錢」，而飛快的汽車是不必要的，說愛德華把自己給了她，而愛德華給她甚麼別的東西都會讓他們的關係失去平衡。
