While traveling in Italy years ago, one of the things that I really enjoyed the most out of the experience was that the local people, when looking at me, were speaking fluent Italian as if I was a local and not a tourist! That was such a cool experience!
I think that visiting other countries and even local regions outside of our norm is definitely an eye opening experience. People these days are so sheltered and isolated in their own bubble that I think it's one of the main causes of issues on so many levels. For example, while traveling recently for the holiday we took, we saw so many different parts of the United States that we never saw before despite growing up here and living here our whole lives. It really opened our eyes to so many different things and it was such a valuable trip and one we will go on again and explore and expand our sphere of experience.
If more people would travel the way you and I have traveled, the less conflict and more understanding I think there would be. I think a lot of the problems of today are because people are sheltered and in their own bubbles, unwilling to be in a situation where things are vastly different and not what they are used to.
