Sometimes, when I'm lonely, I peruse the high-end relationship-wanted ads. Then I feel better about myself, knowing others feel worse. For a little while. This week's best is actually something of a blind item. An ad has been placed in the New York Review of Books, Harvard Magazine, and the Yale Alumni mag, by a "Best-selling Boston author, media commentator (MacNeil/Lehrer, Nightline, NPR)" who is known for her "laser-like intellect balanced by warm heart and disarming ability to laugh at herself." She is an "Ivy educated, Ivy professor." Whoever could this wonderful, lonely lady be?
