CNN: Do you tell people what happened to Youssif?
Youssif's dad: Sometimes it bothers me when they don't ask and they keep just looking. It really bothers me. If they came to me and asked me, I would answer. I would love to answer and tell them what's going on instead of just looking at him. That bothers me a lot.
CNN: Does Youssif ask you to tell him about the attack?
Youssif's dad: He doesn't ask. He doesn't say anything about his face. Nothing bothers him, but it bothers me. I'm doing my best to keep them happy.
CNN: Youssif seems very ambitious and very courageous. What do you think about that when he says he wants to be a doctor?
Youssif's dad: I'm so happy to hear that, of course. Sometimes he comes to me and says, "I know you work like every day, you don't sleep well. I hope one day I'm going to be become a doctor, and then I will buy a house, pay for everything, and then you just rest, Dad." Sometimes when he comes to tell me that, I cry. It just means a lot to me.
CNN: It's been almost six years now since you've been in the United States. What do you think the next five years hold?
Youssif's dad: We don't know what is going to happen, but I hope it keeps getting better and better.
