When I lived in a dorm (more than 50 years ago, sigh), people on another floor kept having food disappear from the fridge. Everyone knew who was responsible, but proving it?
Someone made some brownies flavored with (chocolate-flavored) Ex-Lax. The whole pan’s worth mysteriously vanished—confirming the perp’s identity and providing punishment for the crime, simultaneously.
“Stef is awful, but so far she’s never done something very bad just for the sake of harming someone.”
Stef isn’t anywhere near as smart as Tif (whose intelligence seems to have developed some since high school). I’m not sure how much of Tif’s apparent stupidity has always been total selfishness—but she’s come a long way in that department. She’s often empathetic, now, even with occasional backsliding. Stef is still a total bimbo, but maybe there’s hope for her, too.
I hate to say it, but … Ariana who?
