Or the parents say, "Oh, it's too bad that all that stuff is taking up space in the garage. Let's see what we can do. That's a 3-bedroom house. The upper right bedroom is not needed--so don't put any furniture in it. We'll keep that room as ours, and not yours. After all, you're not paying any rent, so we can't really let you use the whole house. However, you may move all that stuff from the garage into the bedroom, so that you may have more room in the garage. Then close the bedroom door, and don't think about it again."
