There is one strange farang, living in Thailand/BKK

He always writes things like this on thai boys guestbook, and in capital letters:

ANOTHER STUPID IDIOT THAI DON T WASTE YOUR TIMES WITH HIM.

I find it very strange, because I have seen him make the same comment on many profiles, and I have never seen him writing anything nice about another guy.

Well I think it is himself who has a problem, because in fact I have known some of the guys, where he writes his comments, and there have been absolutely nothing wrong with these guys.
