Foreshadowing in The Kite Runner

The first main turning point in the novel is when Amir witnesses Hassan’s rape and makes the decision to do nothing. He just wanted to get to the kite to please Baba. Hosseini has built up to this event by foreshadowing that something will happen that will change their lives forever in a negative way.
Hosseini writes:
“I became what I am today at the age of twelve, on a frigid overcast day in the winter of 195. I remember the precise moment, crouching behind a crumbling mud wall, peeking into the alley near the frozen creek. That was a long time ago, but it’s wrong what they say about the past, I’ve learned, about how you can bury it. Because the past claws it’s way out. Looking back now, I realize I have been peeking into that deserted alley for the last twenty-six years.” (The first paragraph. Hosseini is hinting at what is to come.)
“Speaking those words was like chewing on a rock.”
“I realized I still hadn’t breathed out. I exhaled, slowly, quietly. I felt paralyzed.”
“Kites were the one paper-thin slice of intersection between those spheres.”
“Because that was the winter Hassan stopped smiling.”
“His face was impassive as ever, though something sober had melted into his eyes.”
“But I hadn’t turned out like him. Not at all.”
“You can’t love a person who lives that way without fearing him too. Maybe even hating him a little.”
“I couldn’t tell whether I wanted to hug him or leap from his lap in mortal fear.”
“And may God-if He exists, that is-strike me blind if the kite didn’t just drop into his outstretched arms.”
“If I was going to toy with him and challenge his loyalty, then he’d toy with me, test my integrity.”

On the surface, how does the relationship between Hassan and Amir appear?

Hassan and Amirs relationship appears as though they will always be friends but it will always show that they have upper class and lower class.

“But in none of his stories did Baba ever refer to Ali as his friend.”
The relationship between Baba and Ali parallels that of Amir and Hassan. When you dig down, how is the relationship NOT a friendship? What is it in reality? The reality is that Baba has a larger income and Ali has a lower income and has very little money.

What are underlying social factors at play in this relationship?
Whatever happens they have a very vast caste.

What does this say about our society?
This says that people in society nowadays can only hang out with people that have the same pay grade and we can hang out with people that have a different income, because you’ll never be the same.
