Dead Mouse
Take a dead mouse and while she’s in the bathroom hide it in her bag, that way when she gets home and takes the stuff out of her bag she’ll find the dead mouse and hopefully scream in disgust.
I’m in 8th grade, soon to be 14 years old, the bitch I’m targeting kicked me out of my own friend group leaving me with zero friends but one-fifth grader that I now hang with a lot.
This is just an idea, but I really hope I can do it. The photo is what my cats do to mice when they find them!
