Hi Coka,

Skin colour, hair type, bony structures of the face are distinguishable with some cultures. You know from first glance that they are either from or have ancestors in another country.

I think to the time i was in HongKong and on the subway. Me and my gf stood out like a sore toe and it was pbvious we were tourists!

I'm an immigrant myself - and the minute I open my mouth I'm asked where I'm from!
