My name is Rahim Khan and I am a very close friend of Baba and also his business partner. I spent a lot of time with him and I feel as though he and his son, Amir, are my family because I spend so much time with them at their home. Amir is a very talented young fellow. Although his father thinks otherwise, I see that Amir will go far in life as a writer. He may not know it himself yet but there is a lot of talent locked up in that tiny body of Amir. Life in Kabul had gotten worse and worse because of the Taliban and one day, Baba thought it would be best to take Amir and head off to America where they could seek a better and safer life for themselves. I stayed behind and moved into Baba’s house to take care of it for them. Baba lived the life of a king here in Kabul. He was a very wealthy man and very highly respected by his peers. All of this did not move to America with him. When Baba left for America, he was forced to leave his whole life behind in Kabul. I talk to Baba on the phone every once in a while and I can tell, having been so close to him, that life has become a struggle for him and his son. Money, which was abundant for him in Kabul, here, now is scarce in America. He must work at a gas station for long hours just to keep a roof over their heads and sometimes that isn’t even enough to feed them. I remember Amir was recently telling me that Baba had gotten into an argument with the owner of a market because she was making it difficult for him to make a deal with him to pay her back later. It is not hard for me to realize that life is not easy for him now but he tried his very best to give Amir a good education and keep him happy. All of a sudden, he got sick and was diagnosed with a type of cancer, probably from all the smoking. This did not stop him from working hard for him and his son, Amir. He worked day in and day out until his health didn’t permit him to do so.  He was a very resilient man because despite his obstacles, he worked hard and died knowing that he left his son with a good education, brought him to a safe America, and married him to a wonderful young woman. This morning, I felt the need to call Amir in America. He doesn’t know I know this, before he left for America, he didn’t not leave in a good state of mind. He had a huge burden that h was bearing that he did not take care of before he left, which was his relationship with Hassan, who was his best friend and though he does not know yet, was also his half brother. I know to this day that he wishes he had saved Hassan from Assef when he raped him and regrets not doing anything, but what’s done is done and there is nothing that can be done about it. Hassan has a son, which him and his wife left as an orphan when they were killed. That poor child, Sohrab, is now missing as he has most probably been captured by members of the Taliban. Amir finally has an opportunity to make things right between Hassan and himself by finding Sohrab and taking care of him, to show the love and respect he has for Hassan. I am sure that Amir will take this opportunity, being a little reluctant at first, and save Sohrab, just as Hassan saved Amir from Assef that day. This is why I called Amir today and asked him to come back to Kabul so he could “make things right.”

This webpage consists of an article that talks about a real family that came to America as refugees to live in their dream country and life in a safe country. There are many connection that the family in this article can make to Amir and Baba such as the fact that when they come here they apply for low end jobs which in Baba's case was working at a gas station.
