I just had a discussion with the young woman who rents my spare upstairs bedroom, and she said she was "seeing someone." The implication is clearly that she is romantically - or at least lustfully - involved with him, yet on its face the expression seems odd. Just how much of him she sees is the issue, is it not? The expression used to be common in business, as in, "Mr. Jones will see you now, Sir," or Dr. Bill will see you today at four." There, the implications are qhite different. What parallel expressions are there in other parts of the world? How do you all see "being seen?"
