See how life is. Same thing you can see two different way. Same thing you can see in sad way and happy way. If you see pearl as tear drop it bad for marriage. If you see pearl as raindrop it lucky for marriage. Pearl can be tear or rain. Tear not lucky. Raindrop lucky.
From sand and dirt you getting pearl. From bad thing a beautiful thing is growing inside. Because shell getting upset. Nature is make it protect itself by giving it something so beautiful. Maybe my grandmother is right and pearl is like tear drop. Maybe shell is crying when it upset and that why it making a pearl from its tear drop.
Some people also are same. On outside they having hard shell. They having no choice. They having to protect themself. Sometime even with hard shell some bad thing like sand is upset them. The person sometimes to protect themself is also become bad like the sand.
But some person is protect himself by seeing same thing in happy way. by not seeing sand as way to be upset but as way to make a change. This person smiling even when life get hard and tear drop is coming. That is how he makes the unlucky tear drop turn into a pearl. And then for him the pearl become a lucky rain drop.
