I'm not sure Thais have friends as we know it.
They have people they borrow money from, and they have family.
Mostly they have family in place of friends.
Not suitable friends for us anyway, too lacking in education and general knowledge of the world while thinking they are much better/important than they really are, and at the same time being extremely sensitive and touchy, likely to try and kill you at any moment.
Just my opinion, maybe they aren't like that at all and the problem is me.
