so, we're exploring the idea that 'nammah' is mommy's mommy, just like mommy is pnuts mommy. so she's like, who's daddy's mommy? and i say, gram is daddy's mommy. and she says, well, then, who's daddy's daddy's mommy? and i said, that would be daddy's gram, your great grandma. she said or, my fablious (fabulous) grandma! or maybe my just not bad grandma.
