smile at it

The crescent was glowing in the sky like my eyes glowing on the earth , i have never understood why the world becomes very happy and smiles at us while the overwhelming happiness floods our hearts , but never shares us the sadness , i am wondering if the world has tears , i am wondering does it know what is sadness ?  ?  ? ...
but in fact i do not care , i am happy now and wanna make the whole world with every stone in it happy with me ,smile my world smile , today we just gonna smile ..............................
