Once upon a time in Africa a zebra was drawing a zebra crossing that looked like it with white and black stripes. It was drawing this on the road made by man for fun. A giraffe saw it and asked the zebra to make it beneficial for man -“Let pedestrians or people walking use this for crossing the road. This way the vehicles of man will stop when they see a pedestrian at such a bright juncture on the road.” “Yes,” said the Zebra. The sun heard this and covered all roads with pedestrian crossing using its solar magic.
