The boy in the gray t-shirt is standing next to the girl in the green dress and cowboy hat on the beach.
A man is getting ready to propose to his girlfriend at the beach.
The boy isn't necessarily a man. Because he is standing next to a girl doesn't mean she is his girlfriend or that he is getting ready to propose.
