Before the thread gets hijacked
I know some people still find it hard to distinguish between regular girls on a night out and girls who are "turning tricks". The best way I have found to separate the two is by comparing your looks with the looks of the girl who all of a sudden finds you interesting. If your an average looking bloke and a smokin' hot girl all of a sudden takes an interest in you then guess what? Say no more.
A part of my question that remains unanswered is if it's possible to buy a flat for the same money as it does to rent in Hong Kong or are there many hidden costs I don't know about?
