How does Nadira feel about her sister? How does she describe Aisha in Section 1: Chapter 1?

Aisha and Nadira have never really hit it off. Aisha has always know what she wanted, and at the age of eight, she showed Abba an article about a Bangladeshi girl who succeeded after going to university in America, back when Abba was unsure about immigrating. Aisha always says the perfect thing, and Nadira feels it is difficult to have a perfect sister.
