How do I know I'm a complete nerd?

My overwhelming love of: correction tape Post-It Notes red pens with fine points and mechanical pencils The Chicago Manual of Style The Gregg Reference Manual The APA Publication Manual The New York Times Manual of Style and Usage The New Well-Tempered Sentence (how can I not love something with text like: "Anjula was despondent; she'd come in the wrong shoes.") The Oxford comma and The OED (oh, come to mamma)
