PS: I traveled through Japan from the end of 2017, and returned to Berlin last week. Then I started to learn German(what I have been keeping away from it for 7 years) seriously. 

It has been 15 years since I sat in classroom and study with(as) stundents. My body and mind can not keep up with the changing. I won't be able to get in touch with everything for a while(especially on the internet).

Anyway, May 2018 be a brilliant year for you...!
