My parents house had a door that sticks. It had been like that for like 15-20 years. I just recently went over to their place for dinner, happened to have my tools in the trunk of my car, and decided to fix it after dinner. It only took like 10 minutes of “pop this hinge off, give it a little bend, and try again” to get it hanging perfectly square. Watching them suddenly have to fight +15 years of “I need to lift this door to close it” muscle memory was funny.
