For our work is now mandatory to know, because we have to speak for example with suppliers, entrepreneurs, among others and not know the sometimes throw people. Also for those going to another country have to know the official language of this country because it needs to know to survive. Learning languages is not difficult, but you must be willing to learn from them.
