I am the asshole

My roommate suck. Leave the lights on, runs the dishwasher with two plates in it, does a load of laundry everyday (mind you, 4 of us live there and we all have laundry). Not a huge deal, but we pay utilities and with her being so thoughtless in shared spaces, it adds up. She also bought fugly living room decor and keeps a big ass plant in the living room. Her room stinks up the entire house. I asked if we could separate cabinets and fridge space so everyone is on the same page, she bought a big ass cabinet to keep in the kitchen. She takes up so much space, painfully obvious she has never really lived with anyone else. To retaliate, I’ve been eating her food in secret. I’m actually just hungry because I don’t have much money for groceries even though I work and save. But anyway, she had a banana sitting out, I ate it. Ate one of her breakfast sandwiches, and the occasional snack bag of cheezits. I never take something if her stock is low, but I do take. I don’t even care. I’m just hungry and I hate her.
