i suppose that there are isaan people who are really good people.
i met one once: a real good old geezer who just could not do enough for other people, totally unselfish and genuine.
for all this he was rewarded by regularly being fuckked over by the other village idiots, and laughed at behind his back.
i have many good things to say about isaan people i MET, but almost nothing good to say about isaan people i got to KNOW long-term (above example excluded)
i suppose that if one does not judge them on the same scale as one would judge a person from a civilised country, then some of them are ok, but don't expect any of them to be able to hold an intelligent conversation (even in their own language) or be reliable, punctual, broadminded, honest or be able to drive properly.
