Being impartial or unbiased is what is expected when dealing with issues involving several people. As a teacher for more than 35 years I had to face this situation very often. For example, when valuing answer papers, I could have given more marks to a student with whom I had a soft corner. But, I never did that. Students also knew this. So they never approached me for concessions. Throughout my life I followed this approach and even now continue the same.
