u can say that again.
if a girl doesnt want to accept you, the more you give/do for her,
the more she want to avoid you.
if she likes you, very simple thing you do will make her
happy.
you may try to call her up at 11:59 the night before her bday, you
call her from her house downstair, once she pick up the phone you
sing "happy bitrhday" to her. Then ask her to look down from her
window, hold the cake you prepared with lighted candles, so that
she can see you even it's dark. If she accepts it, she may invite
you to go up to have a slice of the cake. Or she may come down to
eat it with you at the void deck.
