Do you have some kind of challenge with your eyes and your ability to process visual information?
Because I don't.
I was approaching and probably 30 feet away it caught my attention so maybe 5 seconds while i'm thinking is that girl naked from the waist down? And her arse was red, her legs were not. That takes a millisecond to see so it was another few seconds while i'm thinking no, she can't be.
As I walked past she straightened up and I could see she was wearing very short. ill-fitting shorts.
I know what you're trying to do, you're trying to insinuate that I must have been staring.
No, that's how eyes and the brain works. You see something and your brain processes it very quickly. Especially if your focus is drawn to it as out of the ordinary which it was in this case as I though she was partially naked.
It literally takes as little as13 milliseconds (I can link the research) for the brain to process visual information but extracting the details, interpreting meaning and translating that into a decision about what that thing is and what it means takes about 150-400 milliseconds.
No human needs to stare at something to see it and understand what it is. Apologies if you do, you might want to see a Dr.
