Shree Kala Bhairab teacher D.R Koirala then invited Kami to his school, which provided the grandfather with stationary and a school uniform including grey trousers, blue striped tie and white shirt.

"This is my first experience teaching a person who is as senior as my father's age," Koirala said. "I feel very excited and happy."

The school scholarship does not stretch to cover food, though, meaning Kami's breakfast of rice with a fermented green vegetable known as 'Gundruk' must sustain him until dinner.
