what is the matter?

As you know, I don't have any sibling. Because my parents worried that I felt lonely during childhood, they made me get along with cousins. We have a lot of things in common due to similar ages. Who I want to say is one of them. He is one year older than me and a medical student. He has been brilliant since a kid. I hated to compare with him among our relatives when we were young. So I didn't like hanging out with him, besides I thought he looked stuck up. One day he wanted to chat with me on the Internet when I had a hard time to enter a college. He adviced many things to me and I got I misunderstood him. After then, we could hit it off. However he has chaged recently because of his girlfriend !! I'm sad we are the same as us in the past.
