text: The basic language is the language you use at home in your family. \n\nTo answer you question, I think in the language of the country I'm in or in the language I have to use the most in my daily life. Yet, if there are a lot of internationals around, I end up thinking in a mix of all the languages I know and understand (English, French, Spanish, Italian, Romanian, some German, some Hungarian and so on)... and I have troubles finding my words in any of them! It's fun though to talk to each and every one in their own tongue!
