If you are her boss, She has to be very careful with you. If not, you do not need to take her words too careful. She talks with you and surely you should keep her as a friend. In their hearts, they do not really care an Asian colleague. You should know that as well.
My clleague said once, they regarded Europeans as their cousins. Obviously, they share the same blood. Unfortunately, Asian does not have the same concept, such as the relationship between Chinese and Japanese. They set the rules and they rule the world. They always consider themselves as super in their hearts. If you want to marry with them. It is not that easy. It is not saying that you are not good or they are not good. It is a reality.
That is normal. It is their society and they rule. This world is ruled by the White, you like it or not. Racial is a major issue for everthing behind.
