Dear Mr. or Mrs. Drunken Driver,
Please do not harm me or my loved ones. Your poor judgment will not just affect you and your car. It can devastate the lives of people you've never even met. You can take things away that can never be given back. You may even harm my family. All I ask is that you stop and think twice before you walk out of the bar or party or picnic. Ask yourself, "Am I OK to drive?" If you even hesitate before answering that question, get a ride home. You can pick up your car tomorrow. People admire decisions like that. It's not inconvenient to spare innocent lives. You could even be sparing your own. Just consider that you might be a threat to others on the road. Your impaired judgment and reflexes could lead to a terrible accident. You could be arrested. You could go to jail. You could die. Even worse, you could even spend the rest of your life regretting your actions. Just please, please stop and think - "Am I OK to drive?" If you are, have at it. If you're not, please stay off the road and don't kill innocent people. And if you do choose to drive anyway?
Please drive into a tree. They usually win.
