I find that the first language you learn is the easiest, damn I wish I knew Japanese, it's just so hard for me, I learned some of the words and a couple of honorifics, but that's about it.
What I find so frustrating about learning Japanese is that there's hiragana, katakana, kanji and alphabet! Letters, characters, why not just one?! You guys must have pretty huge keyboards if they type in kanji though!
