Thank you s lot sir for you kind words.

although it is true that they often have a "bad reputation" for being a bit rude.

Sir I've got a question.
Let's suppose that you worked night shift and you were awake throughout the night without sleep and food, then during the morning when you're supposed to handover to your fellow nurse who's working on morning shift, a patient came in with an emergency. In this case, sir what will your mood be?would you be happy and friendly?
