One of the good things for men in women’’s liberation is that men no longer have to pay women the old-fashioned courtesies.In an article on the new manners, Ms. Holmes says that a perfectly able woman no longer has to act helplessly in public as if she were a model. For example, she doesn’’t need getting in and out of cars. "Women get in and out cars twenty times a day with babies and dogs. Surely they can get out by themselves at night just as easily."She also says there is no reason why a man should walk on the outside of a woman on the sidewalk. "Historically, the man walked on the inside so he caught the garbage thrown out of a window. Today a man is supposed to walk where he wants so. So should a woman. If, out of love and respect, he actually wants to take the blows, he should walk on the inside — because that’’s where attackers are all hiding these days."As far as manners are concerned, I suppose I have always been a supporter of women’’s liberation. Over the years, out of a sense of respect, I imagine, I have refused to trouble women with outdated courtesies.It is usually easier to follow rules of social behavior than to depend on one’’s own taste. But rules may be safely broken, of course, by those of us with the gift of natural grace. For example, when a man and woman are led to their table in a restaurant and the waiter pulls out a chair, the woman is expected to sit in the chair. That is according to Ms. Ann Clark. I have always done it the other way, according to my wife.It came up only the other night, I followed the hostess to the table, and when she pulled the chair out I sat on it, quite naturally, since it happened to be the chair I wanted to sit in."Well," my wife said, when the hostess had gone, "you did it again.""Did what " I asked, utterly confused."Took the chair."Actually, since I’’d walked through the restaurant ahead of my wife, it would have been awkward, I should think, not to have taken the chair. I had got there first, after all. Also, it has always been my custom to get in a car first and let the woman get in by herself. This is a courtesy I insist on as the per sex, out love and respect. In times like these, there might be attackers hidden about. It would be unsuitable to put a woman in a car and then shut the door on her, leaving her at the mercy of some bad fellow who might be hiding in the back seat.

It can be concluded from the passage that__________.

A.men should walk on the inside of a sidewalk

B.women are becoming more capable than before

C.in women’’s liberation men are also liberated

D.it’’s safe to break rules of social behaviors
