How to make her to talk to me?

First of all, I have to say you might missed the chance already. That's the first thing you should aware.

If you really want to be her friend, just observe more about her, get to know her, find out what she likes, etc. But in a decent way, not like a spy. Your best chance should be having a common topic with her, to make you at ease while you know what you are talking with her also not make her think you are stupid. If you are really too nervous, write a letter, write a card, it's Xmas, maybe a small gift. It doesnt have to be expensive just something you really thought through about it. Show

Communication is a two-ways street. It's harder for you to get close to her as you closed the door once. Now you have to work double hard. Good luck.

Sorry, pressed the wrong button. The small gift showed your interest to her. It doesnt have to be expensive becoz if it is, the girl might think you are just trying to buy your way in. But if she likes expensive gift from a "stranger", I dont think she's a friend that you want to make.

多D幫佢做野ˇ
見佢比人蝦都幫下佢（但唔好幫出面ˇˇ）
借啲意同佢傾下計ˇ
聖誕節寫張卡比佢ˇ
普普通通就得嫁啦ˇ
唔好寫得太誇張ˇ
令佢覺得你有當佢係朋友ˇ
當佢感受到你既關心之後ˇ
你就可以問佢拎MSNˇ
日日都同佢傾下計ˇ
感情一定會更深厚ˇ
咁已經成功左一大步啦ˇ

你地成為左好朋友之後ˇ
你可以搵機會同佢傾心事ˇ
話自己鍾意左一個女仔好耐ˇ
仲要比D貼士佢ˇ
比佢估到你鍾意既人係佢ˇ
呢一刻如果佢都鍾意你ˇ
咁就唔洗煩啦ˇ
如果佢唔鍾意你ˇ
咁你都唔好逼佢ˇ
見返面既時間要表現得自然Dˇ
好似從來冇暗示過鍾意佢咁ˇ
咁佢就會繼續同你做朋友ˇ
否則朋友都冇得做ˇ

希望我講既野可以幫到你啦ˇˇ

好容昜, 其實你兩那麼怕醜, 最好用"信紙", 一張信紙好過十句話

first ,you can talk with her other friends,so you will find the way to talk with her~
when you talk with her friend ,you will know what she like and something about her~
