Everyone will always have their own opinion, beliefs, and ways of living their life. Wether or not you agree with them is not what's important. What's important is that you are confident in your opinions, beliefs and how you live your life; that you do what you need to do, what you believe is right, and that you don't intentionally hurt other people with your decisions.
Your car is Japanese. Your pizza is Italian. Your potato is German. Your democracy is Greek. Your coffee is Brazilian.Your tea is Tamil. Your watch is Swiss. Your fashion is French. Your shirt is Indian. Your shoes are Thai. Your electronics are Chinese. And you complain that your neighbor is an immigrant? Pull yourself together.
