Can't you get it ? Let's put it another example... you are a nurse, & your job is to make sure you give the patient the right medicine... you are sure you have doubled check you medicine before putting in the tray then somebody changed the medicine that can harm the patient.. and you end up giving the wrong medicine.. Patient ended up in severe injuries because of you and people ar pointing on you... What do you think you'll feel ? Anxious, nervous because somebody might have died because of you.
