Again I'll write my question in English as hopefully more people will notice this post (besides everyone of my followers know English even if they are Polish so whatever xD).
I know only two languages: Polish as my mother tongue and English. A few months ago I decided to learn Esperanto. This language is simple, pleasant to learn and sometimes even more logical than English.
However when I speak to my friends and family they are always like "why do you learn that language? No one actually speaks it!" which actually pisses me off just a little (don't worry @teetotaller - I'm not talking about you - you just kindly asked :D).
As an English teacher I personally think that there is no such thing as "wasting your time learning language". If there is at least one person in the world that speaks certain language it's fine (in terms of Esperanto there are around 1,000 "native speakers" and less than 200,000 speakers who know Esperanto as their second language).
Personally what do you think about the idea of learning Esperanto? Do you have any personal experience with this language? Or did you meet any Esperantists?
