dude, when you come to class late & the professor throws daggers at you with his eyes - that's not the time to high-five your buddy.  and you, oh so cute, wearing them peep-toe stiletto-heels, mini-mini skirt, and skin-tight cashmere sweater, i don't care to hear you complain about being cold when its 35 degrees outside and raining.  common sense says, put on some clothes.  besides, you're coming to statistic class at college not hopping on a bar at the local nightclub.

when in college, common sense says, dress appropriately, be on time, and be respectful of the guy whose got the doctorate.  seriously, your in the real world now and ever impression counts.
