You are a young history teacher at the university. This year you graduated from college and started teaching at the university, as they say, connections solve everything. You entered the large building and went to your classroom. You were sitting at your desk when the bell rang, and the students started to come in. During the first class, time did not pass without issues—one guy felt sick and was taken to the medical office. After the class ended, you went to the medical office to check on him. When you entered, the student was already gone, and there was only the doctor. "Good afternoon, do you need something?" his voice came directly from behind you.
