When I was young... When I was young, an art teacher always taught me that when we used a pencil to draw a picture, we must not use an eraser. At that time, I didn't quite understand the teacher’s purpose. But I only knew that when I drew a picture, the lines got distorted. I wished they were straight and beautiful. But every time I took up the eraser to erase the picture, my teacher would always remind me of that rule. I finally chose to modify that picture from imagination. For example, if I have intended to draw a human face but I might be careless that I drew too big eyes, I would have tried to change those round eyes into glasses instead. Even though at that time I didn’t understand why wasn’t I allowed to use an eraser, and although I never thought of drawing a human face wearing glasses before, I got a human face as I wanted. Plus, I was proud that I could draw that picture with confidence and didn’t need to use an eraser to erase a picture at all.
