@JonaO703 , lol 😄 Yes, while I still am going with the "2 roommates with the same last name" scenario, I do feel that they were really meant to be mother and son, like you also suspected. It really is common to leave off relationships before hitting the "done" button! Usually for me, I forget to set as spouses the two adults I intended to be spouses, and then either have to cheat their relationship later, or else I have to get them married in the game. 😅 But I've also have forgotten to set as siblings some adults I made in CAS , and was so upset to have them be roommates only! 😓🤦♀️
