In Canada and the United States, people enjoy entertaining(请客) at home. They often invites friends for a meal, a party or just for coffee and conversation.
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 party on Friday. Can you come?”
To answer an invitation, either say thank you and accept or say you are sorry and give an excuse. “Thanks, I’d love to. What time would you like me to come?” or “ Oh, sorry. I’ve tickets for a movie.”
Sometimes, however, people in the west use expressions(语句) that sound like invitation but which are not real invitation. For example, “Please come over for a drink sometime.” “Why not get together for a party sometime?” or “Why don’t you come over and see us sometime soon?” They are really polite ways of ending a conversation. They are not real invitations because they don’t mention(提到、涉及) a certain 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!” or “OK! Thanks.”
So next time when you hear what sounds like an invitation, listen carefully. Is it a real invitation or is the person just being friendly?
