Honestly, if you think you have feelings for her, tell her. Girls like to be told things like that, weather they feel the same or not. The worst she could do is say no, then you can move on to the next girl. If you don't want to just come out and tell her, try something like writing her a note just saying that you want to get to know her and maybe hang out with her sometime. That will show her that you are interested and willing to take the first step... Hope that helps ;)
as far as i knwo u cant tell how they feel, the best way is to just tell them u have a crush on them coz a crush isnt like crazy I LOVE U!!! kinda thing but neither is it something too small
heres wat chu do my brother::
yew get one of her frands,, or urs.
and tell them oh srry i dont know ur name. but they can be likke ur a cool kid, he really likes u, u wana go out with her. does that make any sense?!
if she flirts back and she has no boyfriend then its a definite possibility that she likes you back. if i were her i wud want to know that someone liked me. ask her out sometime. if u think it would b 2 awkward then ask some1 else to ask her. they just dont have to mention ur name and then c wat she says.
well, first find out if she has a boyfrand before u start flirting with her. if she doesnt then she'll flirt back and smile at you alot. she'll act kinda nervous
well if she likes u she might stare at u during class or something like dat but tell her dat u like her girls love attion like dat and maybe she'll like u bak but if u dont want to go and tell her txt her email her and tell her how u
