求翻译：etiquette is not the same in every culture or in every situation.For example,standing very close to the person you are talking with is quite common in some Asian countries.however,if you do this in Europe,come people might feel uncomfortable.even in china,we all know that etiquette is not the same in all situations.perhaps we think that talking loudly in a library,a museum,or a movie theater is impolite.even if you are with your friends,it is better to keep your voice down in public places.In fact,we should also take care not to cough or sneeze loudly in public是什么意思？
