My native language is not English. I started to learn English only at the age of 12. Then my struggle began, as English and Japanese are two completely different language systems.
When I was 15, I went to a foreign country for the first time. In Vancouver, British Columbia, Canada, I had the fortune of being touched by the warm hearts of people and being exposed to the universe of the English language in the day to day life.
Lots of water has flown under the bridge. Partly due to the internet (it probably gave the definitive, finishing touch), English has now established itself as the lingua franca of the new world, especially on the web.
Thus, people in the world are divided into two classes. Those who speak English as their native tongue and those who learn English later. There are many different kinds of people, for sure, along the spectrum, but roughly speaking, there are those two categories of people in the world.
Shortly after I started to write about general subjects in English, I realized that writing in the lingua franca is actually a way to connect not only to the native speakers of English, but also to miscellaneous people living in various parts of the world, who have learned English as a secondary language. Thus, communicating in English has broadened my world in two significantly different ways.
