Dear Sarah,
I hope you are doing well. Thank you very much for inviting me to the surprise party of our mutual friend, Ayesha Fatima. I really sorry that I will not be able to attend the celebration.
Unfortunately, I have a prior commitment to the same date. Actually, I have to participate an important family event that was arranged several weeks ago, sadly, I cannot change the date. I feel very disappointed about missing the party because I was looking forward to celebrating Ayesha birthday with all of our friends.
Furthermore, I hope the surprise goes perfectly and that Ayesha has a wonderful birthday. As I cannot be there, I would love to celebrate with her another time. Perhaps we could take her out for dinner or arrange a small get-together at a cafe next weekend.
Moreover, please give Ayesha best wishes and tell her that I am sorry I could not be there. I hope you all have a fantastic time.
Thank you for considering my application. I look forward to your response.
Best wishes,
Laila Rubab
