Thank you for your kind invitation to attend your wedding. Accept my heartfelt congratulations on the happy occasion.
I regret to inform you that I will not be able to attend the wedding as I have an appointment with doctor. The date for the wedding is the same as that of the appointment. I wish I could be there to enjoy the festivities.
