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 go but I have to go to New York that day. It's very kind of you to invite me. I hope you will 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 will like it. I hope to see you before I leave.

Nancy

Rose,

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

Nancy
