You think you're turning native when...

[alfeno]

...you add "la" or "ma" when you finish your sentences (while speaking english);

...you burp when you finish your lunch and eat your noodles by sucking loudly not giving a f**k about people around you;

...call for the waitress by waiving your hand and screaming "mgooooi";

...if you are competing with other folks for a taxi, you run for the door handle faster than the others;

...you can correctly pronounce at least 3 brands of beers in Cantonese;

...you know the difference between "char siu pao" and "chu pa pao";

...you never tip anybody and quickly collect all the change (coins included);

...you hardly greet people when you go away or say thank you

...you realize when talking to locals you don't speak English but Chinglish ("M T aR Lo" = MTR / "Bigga" = Big / "Yesday" = Yesterday)

and last but not least

...you go nuts for the stupidest reasons in this world

[alfeno]

Of course, except for the loud burping, all of the above applies to me plus the following:

...when you hand out your credit card or business card with both hands;
...when you start threads or write posts on geoexpat complaining about Mainlanders behaviour in HK;
...when you randomly greet waitresses and cashiers and friends with an as fast as you can "Kung Hey Fat Choy" at CNY;
...when you take it as an offence when they give you forks and spoons in restaurants.

You take offence when your dining partners refuse to share their food with you.

Wearing leggings with everything seems to be your daily fashion option.

Communicating by SMS or Facebook to your spouse / boyfriend / girlfriend only, even if they're sitting directly opposite, or lying in bed beside you.

Posting photos of yourself taken on the street , on random places to be seen as " VIP about town" when the said location may be only just outside your building front door.....

When you let the elevator door close even though the person is few steps away. Or you constantly push the close sign inside the elevator hoping that it will instant close.

Have accepted the fact that ppl do not watch where they walk and literally shove you and start swearing at you because it your fault for being in their way

[Cwbguy]

You used to say Bye
then started saying B' bye
but have now moved onto a fully fledged B' baaii

and you sound very camp saying it.

When get up from your seat in the bus, and the person sitting next to you doesn't bother moving his legs, and then stares at you angrily if you ever so slightly touch him.

You'd rather go for dim sum than a champagne sunday brunch.

You are happy to carry the girlfriend/missus's handbag in public
