With this linguistic diversity, I managed to feel at home in a diverse cultures and environments

The problem with knowing Chinese and Korean is, it can actually put you at a disadvantage, as they then have to put you in a foreigner who knows our language bracket.
In order to deceive/hoodwink they may then start speaking in local dialects or quietly when you around; and yes one woman did this to me in China and I told her to get f****d!!!
