Who am I?

I am NOT
whom I claim to be.
I am NOT a fraud…
I am someone,
if you know who I am,
Then I am….
I am someone
Like the wave of sea,
Washed away the sand
Many a times, yet I am
Never done washing them away!
Like the rain,
fell in the ground,
Washed in the river…
Climbed the mountain… and
Fall again like the gentle snow!

I am just me!! [:P]
