In The Kite Runner, Soraya is General Taheri's daughter. General Taheri is a deposed Afghan military man and considers work to be below his status, even though he has none in California. Soraya is deeply devoted to Afghan traditions, but feels the need to rebel.
Their greatest similarities are their strength of will and their pride: Taheri is willing to give his daughter's hand traditionally to Amir, but will not tolerate his seeing and wooing her at the flea market; Soraya wants to teach and pursues this goal even in her traditional role as housewife and mother. When Amir brings a story for Soraya to read, Taheri takes it and throws it away:
"...it’s my duty to remind you that you are among peers in this flea market." He stopped. His expressionless eyes bore into mine. "You see, everyone here is a storyteller." He smiled, revealing perfectly even teeth. "Do pass my respects to your father, Amir jan."
When Baba asks for permission to have Amir marry Soraya, Taheri accepts because it was done properly. Amir then witnesses Soraya's will clashing with her father's:
I could see Soraya holding back, her face tightening. "I'm not a girl, Padar. I'm a married woman. Besides, they'd need teachers too."
"Anyone can teach."
"At least I'm not like him, sitting around while other people fight the Shorawi, waiting for when the dust settles so he can move in and reclaim his posh little government position. Teaching may not pay much, but it's what I want to do! It's what I love, and it's a whole lot better than collecting welfare, by the way."
(Quotes: Hosseini, The Kite Runner, Google Books)
Her intention supersedes his, and marriage allows her to better find her own path without his undue influence. Both father and daughter want to follow their own path, but feel the other is wasting his/her talents and time in their current vocation.
