Guys, guys, guys, and girls! give an advice:)!?

i live with my parents in a flat on the first floor. i like the guy that lives in the next entrance of our house. he's never seen me and doesn't know. whole my family knows his family, but nobody knows his name, and my family doesn't talk much to his parents. i've noticed him because he keeps leaving his car in front of my window. should i do anything? in russia it's not often when girls come up first. what do you think should be done not only by me, but also maybe by somebody else. well, give an advice. And what should i do or say so that he likes me? P.S. he's 20, i'm 18.the point is that it's russia, it's not usual here for girls to make the first move. and also, how should a girl behave in the conversation with a man? P.P.S. i'm perhaps too shy to make the fist move, and bumpin inot him won't really work, coz there's too much space around.Guys, guys, guys, and girls! give an advice:)!?
Even in Russia it is okay to flirt. Just make a point of going outside when he gets home. At least that way he will know you exist.Guys, guys, guys, and girls! give an advice:)!?
