People who leave the USA are normally a little angry, or very angry with the USA. Or they are wanted by the law, they are the wanted, and the unwanted.
Remember Expats Wanted and Unwanted
This is not an attempt to say good or bad, it is just a notation, maybe remember this when we meet expats, they are often, the wanted, and the unwanted, which can be heard in the tone of voice, and the way they talk. As for me, I avoid people who talk bad about their Mothers, Fathers, children, race, religion, or countries, self loathing is too crazy for me.
