Utility Bills
My roommate used to leave his heater on full freaking blast when he would sleep, and I’ll give you one guess who paid the electric bill. He would sometimes forget to turn it off for work, which of course made me even madder. One day, I had enough. Instead of being an adult and asking him to turn it down and or off when he left, I pulled the heater off the wall and unwired it.
