A cat sitting next to a person who has black pants and pink flip-flops on.
A cat waits patiently for its owner to feed him.
Sitting does not always imply waiting patiently. Just because a cat is sitting next to a person does not mean the person is the cat's owner. There is no indication the person will feed the cat.
