I took an egg from fridge to make egg fry. But, unfortunately, it slipped from my hand to floor. The hard outer shell has broken and the liquid filled over the floor.
Likewise, some persons outer body seems to be very rough and hard. And that outer body compare to the hard egg shell. But he has a very nice heart like an egg liquid(liquid can flow anywhere and to be adaptable/adjustable against anyplace).
Don’t underestimate any person by his outer look..!
