Three young children consisting of two girls and a boy who is holding an apple with a bite out of it, are posing on a scenic mountain view background.
A boy eats an apple that his sisters threw at him in the car on the way to the mountains.
Just because a boy poses with two sisters does not mean they are his sisters.  The apple was not necessarily thrown at the boy.  They boy and girls did not necessarily take a car on the way to pose.  The scenic mountain view background could be a photo background and not necessarily in the mountains
