It's 5:22pm you're in the grocery checkout line. Your three-year-old is writhing on the floor, screaming, because you have refused to buy her a Teletubby pinwheel. Your six-year-old is whining, repeatedly, in a voice that could saw through cement, "But mommy, puleeze, puleeze" because you have not bought him the latest "Lunchables," which features, as the four food groups, Cheetos, a Snickers, Cheez Whiz, and Twizzlers. Your teenager, who has not spoken a single word in the past foor days, except, "You've ruined my life," followed by "Everyone else has one," is out in the car, sulking, with the new rap-metal band Piss on the Parentals blasting through the headphones of a Discman. To distract yourself, and to avoid the glares of other shoppers who have already deemed you the worst mother in America, you leaf through People magazine. Inside, Uma thurman gushes "Motherhood is Sexy." Moving on to Good Housekeeping, Vanna White says of her child, "When I hear his cry at six-thirty in the morning, I have a smile on my face, and I'm not an early riser." Another unexpected source of earth-mother wisdom, the newly maternal Pamela Lee, also confides to People, "I just love getting up with him in the middle of the night to feed him or soothe him." Brought back to reality by stereophonic whining, you indeed feel as sexy as Rush Limbaugh in a thong.
