　　In Canada and the United States, people enjoy entertaining at home. They
often invite friends to come over for a meal, a party, or just for coffee and a
conversation.
　　Here are the kinds of things people say  when they invite someone to their
home:
　　"Would you like to come over for dinner  this 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 to 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."
　　"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 (确定的) 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?
