Decades ago, I needed to cut something in my office at work. I don’t remember quite was it was nor why I needed to cut that paper; it didn’t matter. I didn’t have a pair of scissors, so I wandered out to find a pair. My teammates shared an office across the hall; I made it that far. I asked my teammate if he had a pair that I might borrow. He reaches into his desk drawer, pulls out a pair of scissors, and hands them to me. However, he warns me that they’re left-handed scissors.
“Surely, he toys with me”, I thought. I did not believe that such thing as left-handed scissors existed. I simply took the scissors and started to cut, or more accurately I tried to cut. Though I genuinely tried, I could not get those scissors to function. Obviously, I could pull the blades apart and then back together, but they didn’t cut paper. My friend charitably cut the item for me. I played the fool; left-handed scissors actually exist.
