Grandchildren sometimes have a funny way of saying, "Grandma" or "Grandpa." My son called my mom, "Nina" until he was 3 or 4. Nina came from GRANDMA not Nana, so it's especially odd. I called my paternal grandfather, "Bumpa" for a long time for GRAMPA. But even odder is that my older cousin called my maternal grandfather, "Pak-ak" rather than GRANDPA. So Pak-ak stuck for all future grandchildren and he was forever known as Pak-ak. I sometimes even forget it's weird.
Anyway, this was Pak-ak's dice cup. I use it as a pencil holder on my desk, since I don't really play dice games.
