On the high-speed train from Avignon (阿维尼翁． to Paris, my husband and I landed in the only remainingseats on the train, in the middle of a car, directly opposite a Frenchwoman of middle years. It was an extremelyuncomfortable arrangement to be looking straight into the eyes of a stranger. My husband and I pulled out books.The woman produced a large makeup case and proceeded to freshen up. Except for a lunch break, she continuedthis activity for the entire three-hour trip. Every once in a while she surveyed the car with a bright-eyed glance, butnever once did she catch my (admittedly fascinated．eye. My husband and I could have been a blank wall. I was amused, but some people would have felt insulted, even repulsed (厌恶的). There is something aboutprimping in public that calls up strong emotional reactions. Partly it's a question of hygiene. (Nearly everyoneagrees that nail-paling and hair-combing are socially considered unwise to do.．And it's a matter of degree.Grooming-a private act-has a way of negating the presence of others. I was once seated at a party with a model-actress who immediately waved a silly brash and began dusting her face at the table, demonstrating that while shewas next to me, she was not with me.

Certainly the concern was out of proportion with the number of minutes lost. Peiss theorizesthat it was the blatant assertion of a female practice in what had been an all-male province that disturbed critics. Peiss tells me that after the 30's, pulling out a compact was no longer an issue. It became an accepted practice.I ask if she feels free to apply lipstick at a professional lunch herself. Sounding mildly shocked, she says she wouldsave that for the privacy of her car afterward. Why? Because it would be "a gesture of inappropriate femininity. "One guess is that most professional women feel this way. There is evidence of the popularity of the new lipsticksthat remain in place all day without retouching. It's amazing to think that in our talk-show society, where every sexual practice is openly discussed, a simplesex-specific gesture could still have the power to disturb. The move belongs in the female arsenal and, likeweapons, must be used with caution.
