I'm a language person. I love reading, writing, listening, talking.
Looking back at my secondary school exams, I see five out of seven subjects being about language and literature. Two of them even dead ones (but all the richer when it comes to art, history and philosophy). Well... I guess I just chose what I liked and where I was good at. Math and Chemistry were definitely NO part of that.
After living abroad for a while (is it more than 10 years already?) you realize that, however much you learn, practise and read, things are never going to be the same as with the language you grew up with.
The ease of expression, the choice of words, the flair and rythm of a sentence...getting this right in a foreign language will allways stay more difficult...and I won't even start on the difference between what's witty or funny to a Dutch person in general (and me specifically) versus what's witty or funny to the rest of the world.
At one point the thought even crossed my mind to switch to Dutch in this blog...it would make writing a post a lot more effortless. Not necessarily quicker or simpler but definitely more effortless. But then again, after a year, and with an English blog title. It just doesn't fit (anymore).
So, I happily stick to English and a bit of German, and use my Dutch for a comment or two in blogland, for my email ramblings to friends and family in NL, and for my shopping lists.
