When you stare at nothing, you are staring at nothing. That's explicitly not staring at something. When you are staring at something, you are explicitly NOT staring at nothing, you are staring at the the thing you are staring at. Nobody in the history of time has stared directly at something without looking at it with their eyes......DIRECTLY. Not you. Not me. Not anyone.I'm sure you're familiar enough with English to know that you can stare, perhaps vacantly, at something without actually seeing it, and that this is a common use of the word. How many times have you done this while looking for your keys?
You are confusing staring in the direction of something, with staring at something. Those are two different things. The sage advice didn't say that the elf can hide with someone staring in its direction, but not actually staring at the elf. It said staring at the elf.
You may disagree with the sage advice. You may even change it for your game. But English being English, that sage advice was explicitly about being able to hide while being observed.
