I wanted to elaborate. One time I held up two hangers side by side, with shirts on them. One was hung exactly as I described here. Sideways on the hanger, sleeves toward the front and back instead of at the sides, with one sleeve inside out. The other was hung properly. I asked him if he could see any difference between the two, and he swore up and down they looked exactly the same to him. All he saw was two shirts on two hangers.

He doesn’t see it because he doesn’t want to see it.
