My History with Computer

This is my first assignment for Writing Work Shop.

When I was a pupil, I learned computer in a class. Before I leaned about it, I neither used nor touched computer. Therefore, computer was unknown tool for me.
However, because my computer teacher had enough knowledge and technique to teach about it for students who are not familiar with computer, it was easy to know the way of using computer correctly.
At first, he taught how to use power point. I remember that I made circle again and again, and when he saw it, he suggested, "Why don't you create basketball shape with using circle?" I tried to make it, but I couldn't do it because I only knew making circle. I asked him, "Teacher! I don't know how to make basketball shape!! So I can't do it!" When he heard my complain, he smiled and showed me how to make basket ball shape by doing slowly. Because of his good demonstration, I could make basketball shape correctly. I was happy.
