     In Canada and United States, people enjoy entertaining (请客) at home. They often invite friends over 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 home:

     "Would you like to come over for dinner Saturday night?"

     "Hey, we're having a party on Friday. Can you come?"

     To reply to 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 me to come?" or "Oh, sorry. I've tickets for a movie,"

     Sometimes, however, people use expressions that sound like invitations but which are not real invitations.

For example:

     "Please come over for a drink sometime."

     "Let's get together for lunch soon."

     "Why don't you come over and see us sometime soon?"

     They are really just polite ways of ending a conversation. They are not real invitations because they don't

mention a specific (具体的) time or date. They just show that the person is trying to be friendly. To reply to

expressions like these, people just say: "Sure, that would be great!" or "OK. Yes, 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?
