In college, things are different. We all bate and we all know it. If your college living set-up is like mine, you don't have to lie about what you're doing. If the door's closed and your buddy knocks, there's no need to lie and say you're changing or something like that. Just a simple call of "polishing the trophy!" works just fine. No one's gonna bust down the door and laugh at you cause they wouldn't want the same thing happening to them.
If I don't delete my history nowadays, there really are no consequences. The worst that can happen is if somebody is on my computer trying to look up a song on youtube and they type a "y" into the search bar and some other websites just happen to pop up (YJ and YP, duh). A simple laugh between friends and it's over. I say long live the casual wack atmosphere, it shouldn't be restrained to college.
