A police officer who is present whilst their colleague is killed as a result of activity by a criminal who still goes back to work, day after day, knowing they could be next.
A person who suffers horrific abuse but does their utmost to ensure they do not allow themselves to become bitter and destructive as a result, despite all the anger and hate that wants to boil up inside and spew out.
Someone who will put themselves in harms way to protect, save or rescue another being – either human or animal.
