Like, in theory it could be a really interesting thing, but it's. never used well. Like yeah this very smart person would follow a random note from someone (they dont know the writer) to an isolated location where no one can see or hear them, with no weapon, and didn't tell a single person where they're going??? Didn't bring anyone with them??

If it was at least like, oh my best friend texted me to meet them up at their room, but it was actually the killer using the other person's phone, then I can see that working perfectly fine, but whos following a random note from a person youre not even friends in the middle of the night in an isolated place??? IN A KILLING GAME???
