Z is for Zebra. They don't have black and white stripes on prison clothes these days, they are a bright orange; but they do have black and white vehicles that will take you in for drunk driving, stealing, fighting, and other offenses as a result of drinking and doing drugs.
Everything is not either or, black or white, there are shades of gray. Look out for some of those gray areas, they can keep you blanketed in denial or you can be willing to agree to disagree.
