cuuuuute! though just so you know, the katakana are backwards; what is it supposed to say? I tried reading it and I can't make it out. I can help you write it properly if you want. Since it's katakana I'm guessing it's a borrowed word.
Haha yeah...It's fun. ^^ I saw on the first that it says October in her language but written in kana; I just can't read the backwards characters. XD And the word wasn't English so I was confused. Heehee.
Yeah I think that's what she told someone else. XD Katakana is used for words that aren't Japanese, like English or non-Japanese names or words like "computer" For example, my name in Hiragana is ぐれいbut that's incorrect because "Grey" is not Japanese. So it should be グレー instead. c: Katakana is for any word outside their language spelled out phonetically, or as my sensei says "Japanized" XD
