I think it’s probably the case of it being intutive for them now that they’ve used it. Once one gets used to a process or device it becomes intitutive for them. So it can look strange when people who aren’t familar with said device are struggling. e.g. riding a bike is easy once you know how. At least that’s what it looks like to me.

I think its worth noting that this could be happening right now. Anyone wearing sandels might be subject to someone finding their feet attractive! The horror! :) As a side note, lots of people wear clothing that’s revealing but most of us aren’t up in arms because someone is revealing part of their cleavage. I’m specificlly refering to people wearing pants down around their bum. With there ass cleavage hanging out :)
