@kristabel123 may this give you some ideas!
I deal with toxic people by absolutely FCKIN with them at work.
Swap the sugar with salt...so the next time they make tea or coffee it's game over for their tongue.
Hide the butter in the fridge...people in England love their toast...i hide the butter and jams...and the knives...even if they find the butter...they are forced to use a spoon to spread the butter. If i'm feeling especially adventurous i will only give them forks.
I also hide the tissue paper, so they can't wipe their mouth.
I also mess with their internet USB dongle or wired cables...i unplug their internet cables WHAT IT WASNT MEEEEEEEE I SWEEEAR!!!
I also like to dump smelly stuffs near where my colleagues work (i worked in a kitchen for a looong time...i know how to hide smelly food and then re-materialize them at certain locations....ever tried rotten eggs behind the toilet seat?)
Remind me never to get on your bad side - you're a whole chaotic force of nature. I don't know whether to be impressed or slightly terrified... leaning towards impressed. 🚶♂️
Lol, I'll keep you on speed dial... strictly for educational purpose of course.
