Telephone manners are very important in your daily life.If you want to make a call to somebody ,but the person you wish to call is not in.Generally the person who is answering the call will ask you some question like this:"Would you like to leave a massage ? or "The person you want to call is not in now,Would you make me ask her or him to call you bake again?
But in China,often people don't do like that ,they usually say the person you wish to call is not in ,then they hang up the reciver.This is impolite .
My English is very poor ,let us learn more manners about telephone.Ok?
