With a little sandpaper, you might be able to fix the bedroom-door sound. Eventually, she’ll learn that the nebulizer isn’t going to do anything to her, but she might still want to get away from the sound.
Hope you found the chicken broth!
No sandpaper, no chicken broth. And I don’t feel like shopping. I tried some soup, but only ate about half a cup. Nothing sounds good.
Sometimes door hinges need a bit more lubrication. But a door that "sticks" may be rubbing wood parts together.
A perhaps easier method of dealing with this on a temporary fashion is to use a bit of hand soap, the solid bar kind. Just rub it on the surfaces that are rubbing together.
It's not likely to stain like oil, but it may make the squeaking and sticking go away.
