### Description
Added Dutch quotes.
Dutch quotes translation:
- "Give all your money to the poor people... If they do the same maybe
you'll get it back tomorrow."
- "Remove the word 'me' from the language use and the whole humanity is
perplexed and has panic sweat on their forehead."
- "A James Bond novel is stupid but exciting, while a masterpiece of
Flemish literature is equally stupid but boring as well."
- "I am absolutely against the purity of the language. If it brings
something essential, you should cultivate Anglicisms, Germanisms and
Gallicisms immediately. I do not believe in the thinned-out, which is
presented as the only Dutch, I am irritated by the Dutch domination."
