Disgustingly old - Hugh Hefner and Crystal Harris - 84 and 24
Or just a decade or so older. Madonna and Guy Richie - 50 and 40.
Or a 20 year old and a 40 year old.
I see it as 10-15 years older which isn't horrible but can be an eyebrow raise if the younger is in their 20s. 30 and 50 is better...
Over a large network like a campus or a library. The other day I was watching a video clip on Windows Media and I had some kind of static interference and all of a sudden someone else's video popped up on mine and it was borderline porn.
I didn't know you could tap into someone's WMP like that...
