My brother tells me the Mason-Dixon line is where youse guys meets you all. Yup. It's also the eye contact frontier. The further south you go, the more likely folks will look you full on in the face as you pass. Because it's so muggy, you're automatically exchanging intimate body fluids with everyone within your vapor radius. Might as well smile and nod. And smile like you mean it, not that tight angry little thing people do with their mouths. Let me see those gums, count those molars. Give me a smile like a Golden Retriever, or don't even bother.
