If you’re in grade school, he most likely pulls on your pigtails or puts a frog in your lunch.
However, in a more mature world, I hope he’d say something along the lines of “You seem really nice. Wanna grab a burito?” – and you’re off to the races.
In between those two examples is a whole host of other behaviour that mostly qualifies as bullshit.
Wait for the guy who can articulate his intentions or (better yet) take the bull by the horns and do your own articulating. Nothing ventured, nothing gained.
