Surfing for porn in public places

I'm on a public computer on a college campus, and the kid next to me -- without any hesitation and not a full arm's length away -- is looking at porn. I don't mean to be a prude, but is it necessary to look at porn in a public place? Yes, I saw 'Avenue Q'... I understand that at its essence the "Internet is for porn". But still! As he traipses from site to site, my peripheral vision doesn't reveal if the fare is X-rated or XXX-rated, just that there's lots of naked people in strange positions. I guess today this is college, a place where I'm surrounded by people at least a decade younger than me checking their Hotmail in class on laptops with wireless access. Not all the time of course. Only when they tire of solitaire.
