I bought a new door for my house recently. When the salesman asked what type handle/knob I wanted, I had a bit of an internal crisis. The one he said post people got seemed like it would create a Norman door, which I desperately wanted to avoid. I ended up getting a standard knob to avoid being the absolute lunatic who spent 6 hours debating the merits of various door handles, but had I been alone, I would have absolutely done that. I still feel like I made a mistake every time I look at my door.
The book was a gift and a curse.
