The world revolves around language. This allows for communication and the spread of culture, traditions, standards, ideas, and concepts. We can develop relationships, bonds of friendship, and build families using language. There are some people who prefer to use languages that have been constructed, some for a specific purpose or thematic approach. Some of these constructed languages are Klingon, Na’vi, and Esperanto. This blog is an academic report on the various subcultures related to these languages. Many times people give the argument that this is a silly idea to try to learn a constructed language, but those who use them have constructed a cohesive, adaptable, and diverse subculture that allows for self-expression. Here is a small video of a group of international Esperantists doing what they always do. They are having a great time and meeting new people.
As you can see, one of the reasons people consider learning Esperanto, or any constructed language, is that one of it’s main goals is to create a common secondary language that will allow peoples from a diversity of nations communicate. The goal is not to divert any one national language but to act as a international dialect of mankind.

That was interesting. I had not heard of Esperanto, but this video demonstrated its usefulness. I think the natural thing to have done in this case, was to try Esperanto before she invited the lady inside, however.
