I am a Nurse, not because of the pay; because I love to help and "nurse" the sick. When I wake up I don't say "I have to go to work to day". Instead I say "I get to go to work today". It is an honor to help and serve my patients.
Explanations won't make things better. We feel that we're not even worth a explanation when someone does us wrong. The truth is that the explanation won't change things or make them any better, they will only hurt us more.
