What do you do with stuff that was left at your house by someone you aren't likely to see or hear from again? Do you just donate it? Keep it in case they DO show up wanting their stuff? It's really just one bag of stuff, but I'm living in a very small apartment and it's making me feel weighed down. I feel like it's not mine to dispose of or give away though...but I don't know what the etiquette of this situation is.
ETA: It's been about 9 months since it was left here.
