Why does it always come back to Japanese?

I should go to bed right now... for some reason I just felt like posting because I can. I really miss learning Japanese. I really want to keep learning it when I come back. Vietnamese is interesting to learn and is another language that I can add to my list however, I love the way Japanese sounds! I can't help it...sometimes I want to find a word to say in Vietnamese but when I don't know it the word will pop up in Japanese if I happen to know or remember it. At this point I can say my Vietnamese is beating my Japanese (I am sad about this). I want to see Japan so badly and to watch Gackt in one of his concerts (is a dream of mine), but I think that by the end of the program my thoughts may be more focused on coming home. Who knows? Maybe I will get the travel bug after coming back and may work towards traveling to another country.
