Preface

Once the editor had a chat with some tourists many time they said: "Oooh, your english is very good". There are two possible meanings of this. First, it was true that the editor's English was good enough for them (compared with tourist guide or even becak drivers). Or, the second possibility was because the editor's English was too formal to their ear as if it was a result of an English Course (though the Editor never taken that kind of course actually). For that, the editor just trying to give an alternative reading to they're who wanna learn English deeply.
