Sam,

Thank you for asking me to play soccer with you. But I'm afraid I can't. I have a piano lesson on Tuesday. Maybe another time.

Nancy

Sandy,

Thank you very much for inviting me to your birthday party on Friday. I'd love to come，but I have to go to New York that day. It's very kind of you. I hope you have a happy birthday party.

Nancy

Lucy,

Thanks a lot for your invitation. I'd love to go to your house for dinner on Thursday. But I have to get my things ready for traveling. How about coming to my house with Lily？My mother cooks fish very well. I think you'll like it. I hope to see you before I'm leaving.

Nancy

Rose,

Would you like to come to my house for dinner tonight？All of our good friends will come.

Nancy
