Lark

I play with the light
I play with the dark.
I sing bird songs to the lark
I am jagged and round.
thorny and smooth.
sweet like a sugar cube.
I am here and there.
I am everywhere and nowhere.
I am on and off.
Ion, Ioff, Ionasphere, I am on a sphere!
I am free.
I am illogical.
I am I and I is me.
