Je voudrais juste expliquer que, dans la partie de l'Allemagne d'où je proviens, ce mot ne signifie rien d'autre en anglais que painful and hard work (travail douloureux et pénible). Je n'ai rien voulu dire d'autre.
You picked up on a particular German word that I used, and for which the English translation is ‘dirty work’. I would just like to explain that in the part of Germany I come from, this word implies nothing more than painful and hard work.
