What would you response/speak to some telephone callings? My english is not idiomatic/native, so when someone call me using english, normally I reply "hello" and then wait for his/her question and reply, sometimes, I can't catch up with his/her speed and meaning, I say "pardon"... Although it's ok to communicate with those simple word, I feel depressed that I can't express myself in a more friendly and comfortable way. Maybe the listeners feel my tone quite gruff and impolite... So who can tell me what should I say during such kind of situation, and could you tell me some phrases that frequently used during phone talk? Thanks in advance~~~~~
