Did That Just Happen?

Last Friday, I leave campus, get in my car, and drive toward the exit. As I approach the stop sign, I see a woman standing in my way. This is an older woman, of indeterminate race, in her late fifties or early sixties, with long silver hair. As I approach, she moves out of the way, but as I stop, she comes and taps on my window. Confused, but not wanting to be rude, I roll it down. She asks me where I am going. Guessing that she wants a ride somewhere in town, I tell her that I am headed to the freeway and from there north. Acknowledging where I am going, she responds, "great, you can give me a ride." She then gets in my car. Confused, scared, but not wanting to be rude, I oblige. I drive her to her destination all the while listening to her tell me about what movies I should go see, including the comment that I should see Mamma Mia because, "it is not a guy movie like everyone thinks it is." And she clearly said "guy", not "gay", making it even weirder. At one point, I am unclear as to the directions she is giving me, so I ask her for clarity. She then very rudely asks if she's talking too fast. The whole experience left me baffled and slightly shaken because the woman was supremely creepy. I guess I should just be glad she didn't stab me and steal my car.
