For every individual, sweet can differ in a way. Sweet can be a feeling, sweet home, sweet food, a smile, a gift, a hug or a gesture.
But there is something which is sweeter than all, Water. If a person stuck in a dessert be asked about anything sweet, surely the answer would be water. Definitely, nothing can replace water. Survival can be without food but not without water. A need for mankind and for nature as well. Save water!
