It reads:
ポール先生♥
先生の時々つかうカタコトの日本語めっちゃ可愛いです。(笑)
英語IBの時しか接することないけどこれからも、よろしくお願いします。
It doesn't really translate exactly (which often tends to be the case), but basically:
Paul-sensei,
The *baby talk-like Japanese that you sometimes use is super cute. (lol)
*Although our English class won't continue from here, please remember me.
How cute is that? This is from a girl who is generally pretty quiet - it's always rewarding to hear from the quiet ones. I didn't realize I spoke カタコト (baby-talk, babble) Japanese, but hey, if it helps students remember my classes, then goo-goo-gah-gah, mofos.
Update: Daniel left some feedback in the comments section about the translation of girlie's note:
カタコト can also be written 片言, so it's closer to "broken Japanese" than "baby talk" I think. And it's not that class won't continue, in that second line she's saying, "I only get to see you during English IB, but I hope we can be friends forever!" Or something like that. 接する is closer to "interact with" and "spend time with" than "continue."
So as my first Japanese teacher used to say, "Let's enjoy our mistakes!"
