"You're trading stocks?"
Mike finally showed some interest. He turned around, "You trade stocks too?"
Helen Blair shook her head, "I don't understand these things."
Mike seemed disappointed and turned back, no longer paying attention to her.
Helen Blair found it boring, withdrew herself, and looked at the textbook in front of her. After reading a few pages, she realized it was still like a foreign language to her, though her spoken English was not bad, her reading and writing were not up to par. She took out the large English-Chinese dictionary she brought and consulted it for all the unfamiliar words.
At that moment, she felt a shadow in front of her. Raising her head, she saw two girls walking towards Mike. Seeing them, Helen Blair burst into laughter.
