      It is generally believed that nowadays young people lack the manners that their parents' generation

expects them to have. Although it is true that there is a difference in the generations,I do not believe that

it is fair'to say that today'syouths have bad manners.

     In the first place,the fact that young people do not always shake hands only reflects a move away from

the formali-ties( 礼节)  of the past.  It does not show lack of respect,but simply the present trend towards more relaxed social com-

munication.  Similarly,the way that we speak to each other is surely a manner of personal choice.  Even

though we maynot greet each other formally,this has nothing to do with manners. Youngsters have simply

developed their own greet-ings.

      Furthermore , I strongly oppose the opinion that young people are impolite and show lack of

consideration of others._____,most young people have perfect manners.  Naturally,there are always

exceptions( 例外).  Even older mem-bers of society can be ill-mannered at times.

      As far as I am concemed,the complaints about young people today are entirely without foundation.

Although thereare different attitudes towards manners in the generations,that shouldn't be considered as

rudeness. I suppose that any-one who says such things has not really tried to speak to the young

generation. If he or she did,I am sure they wouldfind that we are just like everyone else.

       To conclude,I think people wrongly regard the lack of formality as bad manners.  After all,

youngsters follow exam-ples set by others,so maybe the world around us has become less formal.
