Yall talking bout how the hws nations wouldn't have human friends cuz they'd just keep dying, but have you considered!! Them being a family friend, as in, being friends with a whole family and staying friends with them as generation keep coming and going.

They'd be that weird "aunt"/"uncle" that's always just sorta there and only God knows why they're here but they're fun and love everyone so we'll just keep 'em I guess. They're that distant "family" member that you haven't seen for a long time but they come in and automatically start commenting at "how tall you've gotten!"

Bonus: it's a good way to show how close and connected they are to their people, and how much they care about them.
