Dear Amy,

    Thanks for your letter. It's always nice to hear from you.

    Today is the last day of my exams. The maths exam is very difficult, but other exams are easy. I'mwaiting for the holidays now, and I'm very anxious to see you and to be with you again. I'm going to spend my Christmas and New Year holidays in New York with my sister. I'm going down town. I'm going to go shopping for Christmas gifts. I'm excited about Christmas, and about seeing you again.

                                                                                                                                                                                                        Yours,

                                                                                                                                                                                                           Jack
