Why am I here?

"Wind," asked the traveler, "why are you here?"

"To push you up the road," replied the wind.

"And I," said the road, "am here for you to travel."

"Wise wind," asked the traveler, "why am I here?"
Puzzled, the wind replied, "So I can push you up the road of course."

"And," said the road, "to walk along my path."

"No, why I am HERE?!"

"HERE is here," sighed the wind.

"So walk along" said the road.
