End of May beginning of Juni of this year I attended a really special event which was the so called Polyglot Gathering in Bratislava. What was special for me is that I was just an average participants speaking 10 languages and I have met Daniel form Austria among others who speaks around 25 languages!
What was especially fascinating for me was that in all kinds of conversations between two pr more participants changed languages after a couple of sentences and partly languages were switched after every single phrase. The “smallest common denominator” were German, English, Spanish, Russian and Chinese which obviously all present participants spoke.
Unfortunately I could only assist for two days but I am going to be back and am maybe going to visit the Polyglot Conference in autumn which supposedly is running in a similar fashion.
If you happen to speak some languages you should absolutely participate in such kind of meetings as well!
