Know You Better

I know someone who always thinks that he is better than me in everything. 

I know that He is correct. 

At first I don't mind, because I agree with him. 

And you know what?? We're friends, and all people know that. 

I never envy him. I always support and cheer him and listen to his every bad situation. 

I never try to be better than him. I like to see that he is proud of himself because he did not have self-confidence before. 

Until... 

When we had a long journey together, I realized that he was not trying to be a better person than he was yesterday. But He tries to be a better one than me. 

Why do you make me your rival?
