Describe someone who you is close to you. What do you admire most about this person?

I have a friend, and he is very good to me. When I have any problem or questions, he always will help to me. He told to me lot computer stuff, sometimes he will show me how is different program works. I remember when the first time he told me about the computer, and he gave me a computer want me to build it and setup the XP. I went home try a lot of times, but I still can not put the XP in the computer. I think this problem for few days, but I still can not fix it. I gave up and want him to tell me the answer. He was laughing when I told to him, and he said I will be very mad after he shows me the answer. He showed me the entire step, and make sure I can understand all things. Everything was good, and there did not have any problem. When we looked at the CD- ROM, there was a problem came. We put in the CD, but the computer can not loading it. Now I knew what it the problem because the CD-ROM was broken. After that he told me, he knew I can easy setup the XP. But he want to told me is do not easy to believe the people how give you the things because we did not knew is the thing work or not. So we had to make sure everything was being well when we get the thing. He is very good to me, and every time when he give me something to do. He will always tell to me the reason and want me to remember also be careful those problems.
