Respected (never use ‘dear’ for elders) Uncle,
I hope you and (insert family details - eg. aunty and the children) are fine. By the grace of (insert God of choice - eg. Lord Balaji) we all are fine at home (I repeat, fine at home). I pray to (again, insert God of choice) for your health and that of the entire family.
Things are fine at our end. Amma’s joints are much better, thanks to your idea of (insert alternative therapy/home remedy). Naanna’s diabetes also is under control now. What would we have done without you?
I am writing to you to convey the good news. I (have passed with distinction/ have been accepted by reputed American university/ am getting married to a Telugu boy my parents have chosen/ am pregnant/ am pregnant again/ have chosen a suitable match for kanna - insert situation you are in). With the blessings of (insert God of choice again. And you bloody well stick to the same God throughout the letter) everything will go on as planned. We seek your blessings.
With this letter, we are sending tickets for the whole family. (Note: the tickets will be ONE-WAY). Please grace the house with your auspicious presence. Also, the mamidikaaya pachhadi you brought last time is over. Tell (insert uncle’s neighbour’s name) I asked about him/her.
Saashtaang namaskaram to you and aunty. Blessings to the children. Amma and Naanna send you their blessings.
I remain
Your loving niece,
(your name – eg. Bhanupriya, Meghalata, Suvarnaratna or anything but a cool name).

Note: You’ll agree this is not English. Not by any stretch of imagination.
