Logical Design...fake sign??

Today's logical design class is in 8:00 A.M. I went to the class in time. There are a few students. Teacher saw that the attendent students were too less. Thus, teacher take a paper make the attendent studuent make a sign of thier name. After every students signed, teacher counted that there are 36 students in the class, but there are 37 signs in the paper. what a terrible thing!! Is this a horror movie?? Where was the fake sign come from?? Then, teacher felt angry and decided to minus all of the students' grade.I felt angry either. I woke up early and went to the class, but my grade was minused. Why didn't I sleep until 9:00 A.M? We can't find who help the absence sign. I hoped the faker appoligize to us, but the faker didn't appear. I real real real felt angry. I wanted to said some dirty words to him. A song from Eminem: Oh my God. I wana fackin' fack. No not f*ck, I said FACK.
