Three years before, I visited the Great Wall with my parents. In the way to the Great Wall, we met a foreign lady. She was happily handing out pencils to friendly students which were talking with her. My mother was asked me to chat her.
Without the second thought, I begin to talk about the warm weather with her. We quickly became friend. I learned that she came to China by herself, so she didn't feel lonely with so many kind people around. Thought highly of my spoken English, she gave me a pencil made in Canada.
