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.
