“Let us assume a quite common situation which some teachers may face. One of the students is about to fail, so s/he comes to the teacher’s office hour and begs for leniency, praises the teacher for his/her great skills and knowledge, and then insinuates that failing a student would not reflect well on the teacher. Unfortunately, the teacher is not impressed and only points out the grades which the student had earned. The student presses on, there might surely be ways to sway the teacher; his/her parents would demonstrate their gratitude for his kindness by making available one of their time-shares, free of charge, and they would throw in even a free flight ticket.”
