The person is alone in the middle of the ocean.
The person cannot be alone if there is a man and woman they are waving at.
The person is either alone in the middle of the ocean or he has the company of a man and a woman.
While the person may be in the middle of the ocean, this person cannot be alone if a man and a woman smile back.
