Why?

Its a bright day

there's a warm feeling in air
every one is happy
no drop of tear anywere

Sun is shining like a cristal
sky is clear like a mirror
everything is perfect
no doubt of any error

Birds are singing melodies
butterflys flying around flowers
mountains covered with greenery
waterfalls seems glowing showers

Rivers flowing with sweet jingles
waves meeting seashore
its a beautifull picture of life
but though our heart wants more

Why?
