If a person asks you to go on a date and you don't want to go, what could you say?
Thank you, but I do not want to do this. Thanks for asking me (and smile and walk away).
You are a store. The sales person shows you the item that you want - but it is costs too much. What do you say?
Hi - do you have another item that costs less? Or - it costs more than I can pay. Do you have sales?
You are out to eat with a friend. She/he has food on his face - what do you say?
You have a little bit of food on your chin. Do you have a napkin?
