A young boy with sunglasses is poised to run while a fair looms behind him.
A little boy runs ahead of his parents towards a giant ferris wheel.
"Runs ahead of his parents" is actually running, not "poised to run". A giant ferris wheel is not always at a fair. If the boy is running towards the ferris wheel, the ferris wheel is in front of him, not behind him.
