In Europe we are surrounded by many languages so when we want to go to some another country, we have to use different language. Of course it's able to speak english almost everywhere but I like to learn at least some sentences.
I speak english and I try to speak german but mostly I only understand german but don't speak. English is easier to learn because I can watch BBC, CNN, english movies... It really helps. But for example spanish? You have to spend long time to find some spanish book in Prague, they have it only in some shops. And they have millions of english books everywhere.
