One afternoon, I didn't leave a classroom after school. I didn't know why. I just couldn't be happy. I felt such awful that I couldn't help sobbing. I thought no one would notice myself. Then, my English teacher came in but comforted me gently. "Try to be positive every day. Learning to relax and smile," she said. These words like a powerful hand, which lifted me from the bottom of the ocean. They were brightly and friendly. With her encouraged words in my mind, I tried to calm down. Finally, I overcome my unhappiness and returned back to my daily life.
