This is actually trivial but I wanted to share since this has never happened to me.

I was walking to the bus stop after work yesterday and noticed this attractive girl eyeing me as I walk in her direction. When I get about 10 feet from her she's still looking at me, making direct eye contact. I said loudly, "Uh oh."

She says, "What, are you too professional to talk to me?" and motioned to my outfit: ironed button-down, slacks, and leather boots. I slowed my walk, but gave her a look of caution. She reached out her hand and says "I'm Kelsey, what's your name?" I said, "Not interested, but thanks." and kept walking. She was stunned.
