I’m a college student living off-campus with a new roommate. I’m not scrounging for change in the couch cushions, but I’m on a pretty tight budget. I have grocery shopping down to an art with coupons, discounts, and sales, and I enjoy cooking, so I usually have leftovers in the fridge. The problem is my new roommate who is constantly eating the food I bought and cooked. I can’t afford to feed her too, but she’s constantly going on about how she “forgot” to go shopping or she “just can’t” because she’s working on a paper. She also buys really junky food, or food with meat in it (I’m vegetarian), so it’s not like I can just borrow some of hers to even things out. I don’t want to be the person who labels everything of mine in the fridge with “do not eat,” but I like cooking a dish on Sunday and knowing all I have to do is microwave dinner Monday thru Wednesday. I wouldn’t have as much of a problem if I could afford a lot of food, but I just can’t. What do I do?
