Dear Varun,

Thank you so much for inviting me to celebrate Diwali with your family. It means a lot to me that you thought of including me in your celebrations. However, I regret to inform you that I am unable to join you this time. I apologize for any inconvenience caused by my absence.

Personal Commitments

I have a prior commitment to attend a family function on the same day as Diwali, which I am unable to reschedule. It is a special occasion for my family, and it is essential for me to be present and participate in the festivities. I hope you understand the significance of family gatherings during festive seasons and the importance of honoring these commitments.

Distance and Travel Constraints

In addition to my prior commitment, I would like to inform you that I live in a different city, which makes it challenging for me to travel to your place for Diwali. The distance and travel constraints restrict my ability to be present for the celebration. I would have loved to be a part of your festivities, but unfortunately, it is not feasible for me this time.

Appreciation and Apology

I want to express my gratitude for your kind invitation and understanding. It means a lot to me that you considered me as a part of your Diwali celebrations. I apologize for any disappointment caused by my inability to join you. I genuinely wish I could be there to celebrate with you and your family.

Alternative Plans

While I won't be able to celebrate Diwali with you, I hope you have a fantastic time with your loved ones. I encourage you to cherish the moments, create beautiful memories, and enjoy the festivities to the fullest. If there is a possibility of meeting up before or after Diwali, I would be more than happy to catch up and celebrate in some other way.

Once again, thank you for the invitation, and I hope you have a joyous and blessed Diwali with your family.

Warm regards,

[Your Name]
