[Nameless]

That is what worries me the most, since I am a foreigner, living in a country were the Japanese language holds little relevance, I ought to find a way to keep practicing them...
The only way I can think of is calligraphy and maybe writing a lot (e.g. books).

I will make even greater efforts not to forget them, your replies relieve me anyway, at least I am not the only one...
