It must be one of my friends. We knew each other on a computer competition and we were teammates. He showed a great talent on math and calculation, but is poor at programming. He is really insightful and interested in all social problems. I learn the critical thinking by talking with him and he inspired me about politics, history and philosophy. To be honest, he plays a great role in my life, making me open-minded and willing to speak out my opinions with less shyness and anxiety. I wanna still be friends with him in the future and I sincerely appreciate him for building up my mind. Hope everything goes well. 😃
