You are dozing on a couch in your university's newpaper office, trying your damndest to not get any work done. Your cheek is a bit itchy owing to the inferior fabric of the sofa, so you open your eyes in preparation to turn over (you don't know why you always open your eyes before you switch sides; you just do). As your vision becomes clearer, you realize that your line of sight is knee-level to a colleague of yours sitting in the opposite chair. Unfortunately for you, your colleague's knees are splayed wide open, granting you an unobstructed view of places better left unseen.
Do you tell your colleague that he has a hole in the crotch of his jeans and let the entire office know that your are looking at his crotch, or do you just let it go, letting your co-worker go all day without knowing that he's showing the world a bit more than he probably wants displayed?
