Roommates share fridges, not the food inside of it! Your roommate should never, ever eat your food, unless you give him explicit permission to. (“Hey, there’s leftover pizza in the fridge. Feel free to help yourself!”) </p>
<p>I do agree with other posters that bringing a fridge and not sharing it is selfish because you can’t easily have multiple fridges in the room. (Official rules aside, fridges take up a lot of space in tiny dorm rooms. I’ve seen rooms where the only space for a fridge was inside the closet.) </p>
<p>That being said, if you bought the smallest variant of fridge which can hold your food and your food only, you might have to be selfish and claim all of the fridge yourself. Just be prepared to trade up for a bigger model to be shared with your roommate if your roommate can’t bring his own fridge (e.g. because the college enforces a one fridge per room rule).</p>
