The library at my university closed at midnight and I had been cramming for a statistics class. I remember that clearly because it was such a hard class, I was late at the library studying a lot for it. The building is clearing out and a big group of us are leaving.
A man, taller than me, wearing a really big coat - heavier than necessary for the weather - sidles up to me to chat. I should point out this guy wasn't in the group leaving the library, he had been hanging out across from the doors I came out of. Being friendly I smiled at him, I'm pretty sure he gave me a friendly look when we made eye contact. He was my age and not unattractive.
He asked what brought me there, was I studying for a test, did I like my classes. It was basic flirting as we walked but he was practically whispering. I was immediately creeped out and answered him with just one syllable answers. He walked alongside my left, a couple feet away from me, then suddenly he was inches from my side, opening his coat as if to engulf me. I never should have let him walk this far, I realized, because the path was on the edge of darkness. If I could run ahead I'd be at my apartment, but then he'd know where I lived...and what if I couldn't run fast enough through the dark practice field?
The sidewalk split and I moved to the right, away from his coat. He's asking me if I was going to take him home with me. I look down and he's wearing basketball shorts and at a glance he's either got an erection or a weapon of some kind. I remember thinking it was impolite to acknowledge it. Some terrible sense of impropriety at saying, "oh my, stranger, is that a baton to bludgeon and rape me with, or just the boner you intend to to the job?" Thankfully there's a light in the building to the right and I veer towards the double doors. A janitor is waxing the floor and I scramble inside and slam the door. I tell the worker there's a guy following me, don't let him know which way I go. He started to tell me to wait and he'll get campus police... Then I ran. I ran full speed through that building, out a side door, cut across a parking lot and ran the long way around campus, lit by streetlights the entire way, home.
My lungs and legs burned and I never looked back. Never studied late again and always rode my bike if I was on campus after dark.
