[quote=renjie1992]How will boys know that a girl is already falling for them? (is my grammar correct? hope u get my point )[/quote] for me, when u are on other girl and she shows acts that u think isn't normal, that is when she is falling for u. when u ignore her, she will just look very happy but inside, she cries out loud for ur attention. when she is attached on u. and when the news reach to u.
