There are some guests from Germany last night, but my Germany colleague didn't speak to them in Germany. I'm curious why he did it. He told me 2 reasons. One is speak some language someone can't understand is not polite. The second is, if he didn't want to talk to him, he would pretend he isn't from Germany.
昨晚有德國人來住但不見我德國同事用德文跟他們聊天,我很好奇問他為什麼,他說 第一:在聊天場合講別人不懂的語言是很不禮貌的。 第二 如果他不想對方講話 他也不會暴露出自己是同一國人。
