Note: We often say something black and white, but there is still a grey area in between. Grey can connect and also cover up many things, sometimes the most important thing is often ignored. This is the grey area between light and darkness. Few people are aware of the enormous impact of the potential self- consciousness of the grey zone. Most of us wear blindfolds and look at everything in a grey view, as Billy Joel, a keen observer of human relations, said: Wherever I go, it's grey with different degrees. The more I find, the less I know. No rainbow shines on me, grey is the color I see.
