Remember your college ID photo?  I vividly remember mine.  In most of my ID photos, i look like i was scared, lol!  I believe, it was how these photos were taken - usually in a small booth we call "photo me" where you sit there and in a count of 1-2-3, a bright light would flash enough to make your eyes grow big.  Those are the opposite of your Facebook profile nowadays.  Everyone prefers to post a cutie pose and use it as their profile pics, am i right?  They look like these!
