Last night, after getting home from a road trip, I ordered a pizza. When the pizza delivery guy arrived at my door, he said, "Are you a doctor?" I sort of stared at him, confused, and said, "Uh, no," and looked at him quizzically. He said, apparently by way of explanation, "Well, you keep such a clean house."
I should note that my apartment was quite messy at the time--within the pizza guy's view at that point were an open suitcase, two empty diet coke cans, a tipped-over tote bag with stuff falling out of it, and some shoes. In no way was my house clean.
What was he talking about? What does house messiness have to do with being a doctor? And why would a pizza guy, seconds before I am about to decide on his tip, insult my housekeeping?
