Query: terrible, just terrible

If you want to learn Thai, you can find much much better books than this. The printing quality is very bad, so that the subtleties of Thai letters are totally lost. The vocabulary is weird indeed -- not the sort of words you will use. I suggest getting the Teach Yourself series' Thai book. Better yet, go to Thailand.Seconds to all comments from the reader from Osaka who writes below.
