To be invisible to detect where they are they would have to be naked so wherever I hear female voices I would shoot paintball so I could make them kind of seeable.
For one, I wouldnt pick my nose or scratch my behind. I would try to act like a normal human being (it might take some practice) Id make up a bunch of stuff about myself that sounded heroic and honorable but not provable. And last but not least, I would pretend I coulnt see them.
The "devilment" I would most likely enjoy would require me to see the guys. :)
~ so I'd be not too excited about everyone being invisible.
This is a difficult question for me on my first thoughts -- if everyone were invisible except me, why would I do anything less than pristine -- since all the invisible people would catch me and I'd not know where any of them were? :)
