I’m not an Indonesian and knew nary a word of it; so, how could I understand what he wrote. I was about to post a thank you message then leave; when, all of a sudden, I decided to read some of his posts. One post is about OctoberFest. It’s about the beer festival that’s being held annually in Germany and in other parts of the world and how it’s being celebrated. Then, I left a comment to this in his Indonesian language.
How did I understand his posts and commented to his post in his language?
