Every student at Monte Vista Christian School take a class with in least one of the “Smith couple”. Students who have classes with all of the Smiths are really luck.When I am a student there, Mr Smith, my math teacher, was famous for his homemade cookies. I can still remember him holding a tray (盘) of desserts tell us to help ourselves. A hard test was always followed by delicious treats, but we even tried to guess the level of each quiz before we took it based on that what Mr Smith had brought in from his kitchen on that day.Mrs Smith was my chemistry teacher, and was knowing for his hard tests and strict discipline .They were such nice couple that before senior graduation, they invited every senior to their house for dinner.
