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,
some 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 our own homes is fine, but there are other places where
talking loudly is not allowed. For example, most people would agree 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.
Although rules of etiquette can often be different, some rules are the same almost everywhere in the
world! For example, dropping litter is almost never allowed. If you see someone you know doing this,
you can ask them, Would you mind picking it up?
