Gender-neutral family relationship descriptors

I was just watching a livestreamer go through the Business and Hobbies pack, and she was looking at the household with old Jazz singer Cannonball, art collector Crispin, and the art collector's adopted kid Ollie. However, in CAS, the streamer hovered over Ollie, and it labelled them as Crispin's "son," which made the livestreamer have a freaudian slip and call Ollie Crispin's "son" and made her think they called them "son" in the lore box. So, yeah, it's pretty frustrating!
