Though what is as sexy, as sweetly taboo as money? So secret, so unspeakable even among dear friends? How much did daddy leave you? How much did you get for that painting? How did you buy that fancy car with no visible means of employment? I have friends who tell me about every kinky sex act, the lies they tell, the crimes they commit, their intestinal complaints. But they shut up like bad shellfish when you ask what they paid for their house.
