SO invited me over to his place for the weekend, even though he's working nights. This is common in our relationship, but he neglected to mention that SD18 was staying with him due to antivaxx BM having COVID yet again. He goes for a deep daytime sleep, and she parks herself next to me on the couch and proceeds to talk at me for the next three hours. She likes to talk A LOT, and she enjoys an audience. I got to hear all about how she asked her mom about how she fell in love with my SO, how she felt it was true love at the time, but now she still cares about him. She'd even give him her kidney if he needed it. SD18 said she heard that SO wants me to move in (I'm not) and said she'd need to be "consulted" about such a major life change.
Long story short, I went the fuck home before he woke up.
