Throwing sand into the wind

She went to the sandy beach to throw sand into the wind.
She threw sand.
She threw more sand.
She kept throwing sand.
Into the wind, which was sometimes stronger
and sometimes milder
and sometimes blew the sand into her face.

"Why are you doing this?" a voice said.
"It's a statement."
"What kind of a statement?"
"It's a concept."
"What kind of a concept?"
"It's art."
"But there's no-one around to watch it."
"That's part of the concept."
"I see."
"Plus there's always the universe and eternity."
