In a word: busybody. Mrs. Fuller means well, and her sympathy for Noelle and her grandparents' is genuine when they lose a loved one. Unfortunately, she's also the kind of woman who has no filter, or any kind of self-awareness, really. She chooses a funeral to question Noelle about things that are none of her business, and truly has no idea how rude she's being.

Woman somewhere between the age of 45 and 60.
