Do you remember when you were about junior/senior high school, we used to put a written paper like ‘Aku Orang Gila’, or whatever, behind the back of our friends?
Do you remember when we were about that age, we like to put gum on a bench, so the next person sat there will ‘suffer’?
Do you remember all those tricks?
And now, ask your friends, who was not at the same school or not lived in the same town. Mostly, they did the same tricks too!! And, i wonder HOW. We had no internet connection to check what tricks students in Jakarta have or Surabaya have, or etc. But amazingly, we’re all using the same tricks! Nobody teached nobody. Nobody spread the tricks to all the school in Indonesia. So, how?
