    Jane, an American teacher, had just started teaching English to a group of Japanese students in the US. She wanted to get to know the students more informally, so she invited them to her house for a party. The students arrived together at exactly 8:00 pm. They seemed to enjoy the party: they danced, sang, and ate most of the food. At about 10:00 pm, one of the students said to the teacher, “I think it’s time for me to leave. Thank you very much for the party.” Then all the students stood up and left at the same time. Jane decided she would never invite them again.
