Talk to him like u would with ur friends. Tell him about the things u like to do and c if he likes the same things. Once u find something in common u can talk about that and it gets much easier after that. i promise.
He will look at you, possibly smile, maybe go out of his way to talk to you or be around you.
let him know you exist through some complex and overintricate scheme to gain his favor
You could encourage him to come and talk to you by smiling and/or winking back, saying hi or maybe fiddling with your hair a bit.
look amazing and talk to him
talk to them, if the feeling is mutual, have at it.
no they dont
You try to make small talk something like: "Fancy meeting you here"
send him a email or letter
well ofcourse they do, do u dream about the guy u fancy?
how do you talk to a cute guy named ashton?
Try to convince yourself he's not worth it. Find someone new.
make him interested in you
