The kite runner chapters 13-15

I think that it was a good idea that they had the wedding before Baba passed away, but usually weddings are more planned out and don't happen this fast. Amir should have really learned more about Soraya's family before he decided to marry her. I thought it was upsetting that they aren't able to have a baby. It was shocking to hear that Rahiem isn't doing very well and he called Amir to come see him in Pakistan. I think it's significant that Amir still thinks about Hassan and how he is doing. Eventually I believe Soraya is going to know what happened. It was sad to hear what Pakistan has become since the Taliban took over, I reallly want to know why Rahiem said that Hassan was living with him? What does that mean? Also I'm curious what the favor is?
