That poor young woman IS VISITING! Just the wrong gender.
I'm sure I'm not the only one who reads "sit at the table and visit" as the womenfolk social activity, like dishes, in families where the menfolk hustle off to a separate place to talk after dinner. By following her boyfriend, this young woman clearly doesn't know her place!
LW, your real family problem is that grandma still hasn't earned the right to settle into a comfy effing chair after dinner and interrogate the youngfolk at her leisure.
My mom was this young woman, only her in-laws didn't suck
