Papa Lai should be Grandpapa Lai

Papa Lai took a morning stroll outside my apartment building and ran into a mother and a cute toddler.  The mother, in Chinese, told her little one to wave shake hands with her "grandfather neighbor" and Papa Lai returned to my place grumpy:

"I was just 'Uncle'!  When did I become a grandfather???"

And then he pouted at me:

"Already called grandfather and you haven't given me any grandkids!"
