マイケルsan has a point.
Especially wrap up expressions are quite difficult to find in any books (in any language course, I suppose).
And, I also liked the fact the series already covered the very-useful-and-yet-difficult-to-find question: is it ok to practice my Japanese?
Foreign language learners always wish to practice with native speakers, but we acutally don't often say this clearly. I'm sure if someone asks me if it's ok to practice Japanese with me, I'd be nicer and more kind
Covering the real useful sentences WITH proper correct grammar is the best thing!
(Some people just focus on "how people actually speak" and it includes corrupt languages and annoying way of speaking. That's disgusting...)
Hope we'll see a lot more of great lessons!!
