And if they insist or do it anyways, that’s annoying but if it means that much to you, maybe deal with it for now and then fine new roommates.
Yes, but I get where you’re coming from. Maybe there’s a cute quilt or blanket that you can drape over the couch that you can wash? But yeah, shared space, and also a couch. Couches tend to be a little gross, that’s just the way it is I fear. I wouldn’t throw any old blanket on the couch tho, I fear then that is dog-adjacent behavior
Disagree. He’s not being obnoxious to make a valid request in his shared space. If the friend doesn’t comply and roommate allows it, that’s also valid. It’s only obnoxious if you try to force your way as the only way. Talk it through, compromise if you have to, but don’t force you way
All you said was you asked them not to do it, which you have every right to do in the shared space. Just as roommate has every right to decline that request or not enforce it. You can walk into anybody’s home and find something that you think is weird. But that doesn’t make them weird for it. Because we all got a little weird.
