Dear Mary, Thank you for inviting me to your party this Saturday. I am sorry to inform you that I cannot make it to your party. The reason I cannot attend is because on Saturday, I have to visit my aunt with my parents that morning, and an appointment with my doctor that afternoon. Also, I have to study that night. I am so sorry I cannot make it to your party. Thanks again for inviting me, Mary!
