I'm not sure why you believe I'm trolling. I like learning new languages, but in the end it would be impossible to learn every single language in the world (especially when going there for a few weeks).
I always learn the most basic phrases, but when it comes to general communication I've always fallen back on English, which has been no problem during my travels in most of Europe, USA (duh), Morocco and some South American countries (I do know Spanish as well, but my friend does not, so we still talked a lot of English there).
Not sure why it triggers you when I simply ask about how easy/hard it is to get by using the biggest lingua franca in the world. If I had three wishes, knowing every language by heart would be one of them, but we don't live in such a world, and learning a new language fluently, especially for a two week vacation, is quite an achievement
