Just An Annoyance
Fantasize a situation where every time you leave your room, you have to turn your doorknob up just to be able to close it… if it’s even able to turn up. Otherwise, you’ll never have any privacy. This is very annoying to deal with but an easy fix for someone with good handiness skills.
It would just take a screwdriver to unscrew this doorknob and place it the opposite way. If you don’t have the skills to do that, you can hire a contractor. Whenever you move to a new place, you are guaranteed to find problems, so this homeowner should be considered lucky.
