Back in the university days, I've read a few texts on language acquisition and almost understood some of the mechanisms used to learn a foreign language. I enjoyed learning about learning. A lot of reading helped me out with English and a lot of practice allowed me writing some comprehensible articles.
Nowadays, I am faced with the inverse phenomenon: language de-acquisition. I never knew it existed. But after years of non-practice, I don't have any conversation skills in English and I just found out that I am getting worse at writing too. Silly me that thought that it was like riding a bike: never to be forgotten.
I diminished a lot on the diversity and volume of reading. Today it takes me too long to write a few paragraphs. And when it is done, it does not make much sense and is riddled with mistakes. It sadly reminds me of a joke we use to tell on a guy that went into USA, could not learn some English and came back home... dumb. Disgusting.
