A little boy in a pirate costume is running behind a little girl in a princess costume carrying an orange pumpkin along the sidewalk.
The kids are sitting in their desks during class.
It is not possible for humans to be in two places at once (along the sidewalk, classroom) nor is it possible for anyone to be running while also sitting.
