Miss Dasgupta! Pathetic! Deplorable! People are sad or passing condolences not because Prof or Minal anyone of their use. They are feeling sad about it. Life is not all about calculating usefulness/non-usefulness and then reacting.
You Lack emotions! Sorry to say if someone else around you'd die we will be sorry you better take your pen and paper...calculate your IMPORTANCE of dropping 5ml of tears & react! Gud Luck!
