Everyone has different names for their grandparents, it would be interesting to see what people have for them... nicknames and such.
See, my grandmother being chinese... I use the chinese word for my mothers mother... which... I don't know how to spell.. it's like Popo or something... pronounced paw paw I think. And my uncles children would call her Gong gong I think... ços it's their fathers mother.
And if I had ever met my fathers mother, I'd have called her Grandmother Jane because that's how my dad refers to her when he talks about her to me
So ^^^ question in the title
