Grandparents are good for the pocket. They buy toys that Kai wants so that we don't have to. Here's the extensive Thomas & Friends set that we now have in the living room.
Kai has plenty of reasons to cheer.
But seriously. I like the fact that Kai has an opportunity to interact with his grandparents, especially his paternal grandparents who have been instrumental in bringing him up. I wasn't very close with mine mainly because of a language barrier. My parents didn't teach me any dialects (Cantonese and Hokkien), and I was very shy as a kid. I am sure there were plenty of stories they could have shared with me about their past, but I'll never know them now.
