If she likes you, she will talk to you alot, look at you alot, flirt with you, laugh at your jokes. . .even the lame ones and she will smile at you alot.
If she likes you then you will most likely get dragged into a corner and snogged until your dead
ask her who she likes
Get to know her.
this is simple get to know this girl
If a guy look at the girl twice then it means she likes the girl
That means he girl likes you and answer that question by telling the girl something she likes to do. If you don't know what the girl likes to do then you're a goner
Ask her.
If no on likes you
ask her out
I gess the same way you can tell if a normal girl likes you.
if she talks to you and touches you on the leg or something like that. then that means she likes you.
go to 'ask' and type in 'how do you know if a girl likes you' you should find all you need there
