Why 個朋友拖個鬼妹女友出去, 好多人望佢?

Because people in HK dont see a Chinese with an American (or whatever her nationality is) quite often and they are just simply curious. It is more common to see people of different races together in Western countries such as America and Canada.

ex: my cousin is dating an Italian and I'm dating an American

係呢度少見我地d中國人拖住d外國人...
新奇呱....

好樣眼 ! 比著你都會望 !
