How do you write a letter to grand father telling him how you celebrate Diwali?

Dear Grandfather,

I hope this letter finds you well. This Diwali, we decorated our home with colorful lights and rangoli, creating a joyful atmosphere. We shared delicious sweets and snacks with family and friends, and in the evening, we performed a small puja to seek blessings. It was a beautiful celebration filled with love and laughter, and I wish you could have been here with us.

With love,
[Your Name]
