As we go through life, let it be in any sphere we come across many issues and dilemmas where there is no black and white solution, most of the time it's grey. Sometimes even the problem itself is messy and unclear and does not fit in a standard box of white or black, right or left. To think of the solutions to these issues clearly we have to walk on central path, weigh the different paths, discuss the pros and cons of arguments coming from different sides of the Aisle and then take a stand.
That's why "The Zebra Crossing", which enables us to look at both sides of an argument just like we see both sides of the road while crossing the road and then walk straight ahead on the central path. As there are equal numbers of white and black stripes on a zebra crossing, we should be impartial and weigh both sides equally.
