Dear [Sender's Name], I hope this letter finds you well. I recently received your invitation to the social event happening in Wayne, Michigan. I want to express my gratitude for considering me to be a part of this celebration. However, due to prior commitments and personal circumstances, I regretfully decline your invitation. Although I would have loved to attend the event and spend quality time with you and other attendees, I am afraid I will not be able to make it. [Provide a brief explanation here if necessary, such as time conflicts, other obligations, or logistical reasons.] I sincerely apologize for any inconvenience caused by my absence. I am sure the event will be a great success, and I regret missing out on the opportunity to be a part of it. Please convey my warm regards to everyone present and extend my best wishes for a delightful gathering. I hope that in the future, we can have another opportunity to share some memorable moments together. Thank you once again for extending the invitation. I appreciate your understanding and kindness. Warmest regards, [Your Name]
