" In Tariq's grimace, Laila learned that boys differed from girls in this regard. They didn't make a show of friendship. They felt no urge, no need, for this sort of talk... Boys, Laila came to see, treated friendship the way they treated the sun: its existence undisputed; its radiance best enjoyed, not beheld directly. "
― Khaled Hosseini , A Thousand Splendid Suns
