One student, who did not come to my class 14 times since the beginning of the semester, had visited my office yesterday. Upon listening to his explanations; could not wake up, busy, I wanted to come but could not make it and bla, bla.. All I said to him was "You are rude and no attitude!” He was staring at me unbelievably with mouth wide open.
Before he left my office, he touched his cheek and asked me " Am I rude?". I said " yes, without your knowledge you are doing this to your teacher.." He left and I left him as well..with no grudges. Sometimes, you need to say this so that he will stop dreaming..
p.s. coincidence is a miracle of Allah..
