Invader Stu: Oh... You're English!
I have come to the conclusion that the Dutch have a very special ability. It might even be possible to call it a super power. I am not sure if it is a skill that they are born with or one that they develop naturally over time, but it is something that I have encountered a lot.
That English cough
Every time I try to speak Dutch with an unfamiliar Dutch person they are able to detect, analyse and identify my accent before I’ve even fully formed the first syllable of the first word of my sentence. It is entirely possible that the Dutch can hear my accent as I breathe.
"Ohhh. You're English," they will often interject as I stand there with my mouth open, having only muttered the sound "umm" or "err" or simply having coughed.
They even managed to say it with a hint of surprise that suggests they should have identified my accent sooner (before I entered the room for example).
Accent detection instincts
It is either a form of super human hearing that allows the Dutch to do this or they have just had a lot of practise hearing people mangle their difficult language beyond recognition.
The second option seems more likely because it is probably something that happens so often that they have been able to fine tune their accent detection instincts.
Maybe they have even learnt to identify certain mistakes with certain countries (thus aiding the identification process).
"Oh. You pronounce the "ei" sound as "aaa". That’s a classic English mistake."
Wherever I go in Holland it is almost impossible to say anything in Dutch without being immediately identified. This must make life very stressful for any spies who are trying to lay low in the Lowlands.
They must be in constant fear of detection just from having to have a casual conversation with a passer-by.
Even at an early age Dutch children seem to have this special power. Have you ever attempted to speak Dutch to a small Dutch child?
It rarely goes as you expect. In my experience they might not be able to identify your accent yet and they might not even be able to fully understand that there is such a thing as a non-Dutch person but they will know something is wrong.
They know it just by hearing your attempts to speak the language that, they themselves, have not even fully mastered yet. Then they will just stare at you in an awkward silence (awkward for you, not for them) as if waiting for you to stop being strange and start making sense.
No one can hold up to that kind of pressure for long and if you are a spy there is no dignity in having your cover blown by a three year old.
