I'm sorry, this article is not about animation but my daily life. I worked long time yesterday. I got to my office about 9 o'clock and left around 22 o'clock. I taught 5 students. Almost all of them were taught mathematics by me, but one of them studied English. I'm a college student majoring in algebra. So I am good at math and I can teach them. But English is different for me. Now I enjoy to study English, but in my high school days I don't like this subject and am not good at it. Poorness of English is one of the reasons why I missed to pass the exam to enter University of Tokyo. So I feel sorry to the student in somewhere on my mind anytime to teach. I will study more!
