I dreamt a chemistry teacher who taught in our school for a short period of time. She treats everyone well. If I didn’t see it, I wouldn’t believe there’s such a big difference between people. For example, she shared her snacks with the cleaner who was on night shift. She even invited me to her place. In winter, her cooking brought warmth to me — a person wanders from place to place. After her quit, many people asked me and shared memories about her. On her last day of working for the school, she said she wanted to go to the hospital with me. I knew that because she wanted to shared the cab with me. She even waited for me and called me in the hospital. I said, “I won’t go with you. I’m going back to Tianjin.” She said farewells, then turned and went. I couldn’t stop my tears and dared not to watch her retreating figure.
