Down pillow in a washing machine... what could go wrong?
How many of us wash our clothes by hand? Scratch that - how many of us have ever washed our clothes by hand? I'm betting that the answer is close to zero (especially if you're a millennial). Judging by the fact that you're reading this now, you've probably got access to utilities more necessary than the internet, i.e. a washing machine. So what's the big deal? The big deal is that there's a monkey in India that can wash clothes way better than you can. And monkeys don't even wear clothes (well, not naturally). How does that make you feel?
The only good thing about having a roommate that steals your stuff is that if you tamper with your own stuff, they're in no position to complain about your stuff that they deny taking. This is a pretty common tactic. A similar and more explosive thing happened when this food thief's roommate switched to regular milk.
