you should tell her or just move in for a kiss! just kidding! i am a girl and i would konw! be nice to her and write her a note saying how you feel.
Tell them if you like the girl tell them if you dont you will be miserable if you dont!
It's not polite to ignore someone, tell them politely to leave you alone because you dont like them, dont ignore her because then she will just bother you more to know why you are ignoreing her..
If you cant tell the girl directly that you like her simply look into her eyes evrytime and she will get the message
try to get her alone with you and tell her how you feel
well find a time when your alone and tell her how you fell
Ease your way into it dont rush and take time
Quietly, alone and tell it like it is.
Tell that girl to leave you alone, because you like someone else now...
if your a guy you have to make the move if your a girl wait for guys if u like a girl tell her to not tell anybody that u like her girls dont tell anyone
Ignore them or tell them to get lost.
First you start of as a normal freindship then when your alone ask her if she says no don't get serious like flowers chocolates that's sort of thing just get over it
if you feel that they like you or like being around you, you should tell them but dont say it when there is people around tell them when you guys are alone or when you have the chance or at the right time
