Hi everyone ! My Husband'a Brother's gf is a foreigner (Indo Chinese ) . Whenever there is a family gathering, She will always put on a fake front and try to be polite and gentle to the relatives. There was one incident she greeted all the relatives by their title and ask them to eat dinner one by one. It is very irritating as we Singaporeans women do not behave in this way. All in all, I have never seen such a fake person. How can I deal with her ?
