It's a general command.  It's one that tells you, "hey.. take a look over this way." But honestly what is it about one's face that would cause them to pay it any mind?  I don't ask because there isn't anything. I ask because there are so many things that i've become curious as to which you think is paramount.  If you want to talk about mistakes--if you want to talk about missteps, don't walk a mile in anyone elses worn and faded shoes.  Walk barefoot.  Feel the way the rocks want to be a part of your sole so bad that it hurts you.  Walk a full mile without your shoes.  It just plays the heartstrings of society when you try to do otherwise, and tell of how it's changed you.
