"To the thin, blonde girl at Glenbrook station most mornings, you are the prettiest girl I've ever seen... I'm the guy smiling at you. Want to go raving?"
I'm sure a lot of them are piss takes, but for the people really putting themselves out there it's quite scary. Bravo to you I say. Using words to woo is sexy, even if MX is your medium. Maybe you could up the anti and actually write them out on a piece of paper, like a proper love letter, and slip it in the bag of your train-girl-crush! Now that's romantic.
Then I'm sure she would join you in your rave cave.
