    Here are the kinds of things．people say when they invite someone to their homes。

    “Would you like to come over for dinner this Saturday night?”

    “Hey，we're having a dinner on Friday．Can you come?”  

    To answer an invitation，either say thank you and accept，or say you're sorry and give an excuse：“Thanks，I'd love to．What time would you like us to come?”　or “Oh，sorry，I've tickets for a film．”  

    Sometimes，however，people use expressions that sound like invitations but they are not real invitations, such as ,”Please  over for a drink sometime．”　or　“Why don't you come over and see us sometime?”

    They are really polite ways of ending a conversation．They are not real invitations because they don't mention a nice time or date .They just show that the person is trying to be friendly．To answer expressions like this，people just say：“SURE．That would be great!”，“OK．”　or　“Yes；thanks．”
