Answer 1

Dear Mary,
     Thanks a lot for your invitation. I'm sorry that I can't come to your party this Saturday. I'm really
busythat day. I have to go to an English contest in the morning. In the afternoon I am going to the soccer
club. After that I'm going to my grandfather's house to have dinner, because his 70th birthday is on the
same day!    
     I wish you a happy birthday.
                                                                                                                                             Mike
