We had a great conversation in Japanese. The particle after time words was sometimes forgotten, but they were able to self-correct it. たいへん　よく　できました！

「こ、そ、あ、ど」も「・・・の」も「・・・も」も　パーフェクト　です。でも、Particles　は　パーフェクトじゃないです。Please do not forget particles between words. Apart from that, perfect!!

Although I am from Seoul and use 표준어(표준말), I travel back and forth pretty regularly for work, so I get exposed to certain dialects. He showed an interest about one of them. we compared it with 표준말 and practiced it together. We reviewed everything at the end of the lesson and I asked him a lot of questions repeatedly, I got the feeling that he has the knack for languages because he got almost everything right. He could even think of a different example to use the expressions we learned. His Korean is brilliant and we had a lot of fun.=]
