I don't remember where I was reading this, but whoever posted on the page said something along the lines of there being a fallacy that means:
believing a task to be easy for others because it is easy for you
I looked it up afterwards and found other references to it, so I believe it is a real fallacy and not just something that person made up. This has been stuck in my head for weeks so any help is appreciated.
