Ladies Staring As Other Ladies Stand

My time spent milling around at my high school Ive noticed something that i think every girl does. You can be siting in the commons area or wherever you are that there is a mass, mixed sex number of people and watch. Say at my table there is just me and 4 other girls, (not that im like gay, or a womanizer, or anything, i just know 2 of them and that's just where Ive sat since 9th grade; the other skank girls just managed to migrate to "my" table this past year) one girl can get up to go empty her tray, say one of the ones i know and one of the trailer trashy looking girls' eyes will follow the other girl, up and out of her seat and follow her back into her seat when she returns. I see this and i watch those trailer trashy eyes, watching the watcher. All girls will do this. They are simply sizing up the other same sex animal. Not that there all lesbians, its just a natural girl thing to look at another female and judge them, compare themselves to them like, "Oh man i am glad my ass isnt that big" or in like one of those really sassy girl tones " Oh my god, i cannot believe she would wear that out in public, hmphh what a tramp". ..
