Just as you, I live in Flanders. I get calls in English, French, even Spanish. Sometimes even in Dutch. In my experience, the English and Dutch speakers hate French, while the French and Spanish speakers hate Dutch. So you choose whatever they hate most and start asking about their favorite brand of toothpicks or whatever untill they fold. Double the fun when they find someone else speaking your language, at which point you switch to another language. Or go to pig latin.
