People are looked on as nerdy, tough guys, criminals, successful and unsuccessful based on their "packaging." Just like the batteries were still great despite the package being damaged, some individuals are the same way.
Ignorance prevails and it instills in us all that we should not have our own sense of individuality, but instead that we are expected to be identical to others whose skin pigmentation is the same as ours.
I've got to be honest. I am not a huge fan of "sagging." I hate to think that I'm an unenlightened, fuddy-duddy in my own frustration with this particular style. But, my objections may be more nuanced than most.
