Du wanna know how to impress a woman: KISS her, hug her, compliment her, Liebe her, tease her, protect her, support her. How to impress a man: turn up naked with beer! that's just the way I see it :/
Girls fall easier than guys do. Sometimes if they just smile at a girl oder Kommentar them in anyway the girl can go crazy for them even if the guy don't like her.
Girls are crazy like that.
All I can say is if Du don't see any effort in the guy talking to Du oder anything then don't fall for them.
To impress a girl Du gotta have charm... And when a girl begins be sweet and kind. It'll get Du far... ;) (that pic is of me and my brother performing in our band XD)
