While it pains me to decline, I have a prior commitment that coincides with the mentioned date and time. Due to this pre-existing obligation, I find it impossible to rearrange my schedule to accommodate attending your event. Please don't mistake my inability to attend as a lack of interest or gratitude; I genuinely value your friendship and support.

I am confident that your social event will be a resounding success, as your attention to detail and impeccable hosting skills are widely recognized. I apologize for any inconvenience my absence may cause and assure you that if there was any other way to participate, I would gladly seize the opportunity. However, I would be absolutely delighted if you could share some pictures or highlights of the event afterward, so that I can feel a part of the occasion in some way. Please accept my best wishes for a memorable and enjoyable gathering, and my sincere apologies for my absence. Once again, thank you for your gracious invitation. I hope to have the pleasure of attending future events hosted by you and to spending quality time together on alternate occasions. Wishing you a wonderful time ahead! Warm regards, [Your Name]
