We all get that saying. What the fu#k. Things go wrong. Shit happens. Situations occur and we have to face it. The fear that something bad may happen at that particular moment that scares us.
Whatever it may be. We got to remember, be it any person from any country that you come from, there's always the bully's and the bullied. You're no longer in High school. Wake up. True to the fact that if you're in a foreign country, you don't want to piss anyone off, but hey you may be in a bad situation that you never could have imagined. Well may be you did imagine but it became worst, so what do you do? Think about it.
Bar advice. Be humble.
