Love of nature...
Rain is not only drops of water.
It is the LOVE of sky 4 earth.
They never meet each other but send LOVE this way.
Enjoy the LOVE of nature... :)
Defination of love
What is LOVE ?
Love is when my mom comes to me at night & say
"Beta,
I love you"
Love is when I come back from Collage & papa says
"Beta,
late hone wala tha to call kar deta?"
Love is when my
sister says,
"Bhai,meri shadi ke baad mujse jhagda kaun karega?"
Love
is when I'm moodless & my brother says,
"Chal kahi ghumne jate
hai"
Love is when my best friends call me & say,
"Ooe !
tere bina dil nahi lagta"
That's love...
DONT MISS IT IN LIFE
